Show notes What is “Diversity” & “Inclusion”? Facets of diversity are all aspects of human differences.  These include gender, race, ethnicity, age, physical ability, gender identity, national origin, language, religion, sexual orientation, socioeconomic status, and more. Inclusion is making everyone feel welcomed and included. Inclusion requires having a culture & environment where everyone can thrive regardless of background differences.  This inclusive culture fosters respect & belonging in which we hear, appreciate, & value everyone and their perspectives. Inclusive organizations work with individuals to recognize and eliminate both explicit and implicit biases. They may do this with intentional efforts like professional & skills development as well as addressing awareness, education, and policy.  Diversity measures representation by counting the presence of varying identities and characteristics. But Diversity itself is not the final goal. Diversity is the metric while Inclusion is the goal. For now, while representation is so disparate among certain groups, diversity is an important metric. It’s hard to be truly inclusive with such professional inequities.  “Ultimately what we want is for people to belong. So not just be asked to the dance and sitting around and staring at everybody else but really feeling like you can go out on that dance floor and dance, like nobody’s watching and it’s fine because this is your  community.” – Pamela Douglas Why is achieving diversity important? Diversity is a virtue in and of itself.  But more than that, diverse groups make better decisions, are more innovative, are better at problem solving, and have an expanded talent pool. Cardiovascular medicine benefits from having a diverse workforce. Science performed by diverse groups has greater scientific novelty and produces higher impact papers in higher impact journals. Is there a link between professional diversity and healthcare inequities? YES! Physician diversity reduces healthcare disparities and improves healthcare quality. Physicians who train in diverse environments are more culturally competent when treating underrepresented groups. Underrepresented physicians are more likely to serve underrepresented populations. Underrepresented patients are more likely to follow the recommendations of physicians who look like them. This enhanced trust is critical to an effective patient-physician relationship.  In the context of clinical trials and guidelines, underrepresented physician scientists help diversify our clinical trial participants, resulting in a more robust and representative evidence base.  How are we doing in cardiology with respect to diversity? There have been improvements but we have a long way to go. Women comprise 43% of internal medicine resident physicians by only 22% of general cardiology fellows and even lower proportions within procedural fields. Underrepresented minorities–specifically Blacks, Hispanics, and Native Americans–make up about 32% of the US population but only 13% of general cardiology fellows. Benchmarks for other racial and ethnic groups and for other facets of diversity like socioeconomic status, sexual orientation, gender identity, IMG status, and others are even less clear. Inequities amplify in advanced career and leadership positions.  Only 11%, 9%, 11%, and 24% of Asian, black, Hispanic, and white women, respectively, are full professors compared with 21%, 18%, 19%, and 36% of Asian, black, Hispanic, and white men, respectively (Albert 2018). In the top 40 ranked cardiology programs, there are no female cardiology chiefs (Albert 2018). There were no women editors-in-chief for US general cardiology journals between 1998

Cardiology Programs Twitter Group created by Dr. Nosheen Reza Patient Summary A woman in her late 80s with history of systemic arterial hypertension and dementia presented with 2 weeks of nausea, vomiting, confusion, and yellow-tinted vision. When she presented to the hospital, initial history was limited as her caregiver was unaware of her medications and medical history. An initial ECG showed isorhythmic A-V dissociation and scooping ST segments laterally. Given her clinical history, this raised the suspicion for Digoxin toxicity, and a serum digoxin level was significantly elevated. However, this was not a home medication for the patient, nor did she have access to it!

Initial ECGB. CXR- Patchy opacities of the left lower lobe consistent with pulmonary edema and/or aspiration​ pneumonia.C. Repeat ECG: AF with AV block, persistent scooped T waves​D. Post arrest ECG: Flutter/fib with AV block, VERY LONG PAUSES up to 6 secondsE. ECG post TVP: A flutter, slow V response (pacing picking up), intrinsic ventricular rate 20-40, PM set to 50 bpmF. Most recent ECG: Normal sinus rhythm TTE Episode Schematics & Teaching The CardioNerds 5! – 5 major takeaways from the #CNCR case 1) This episode featured a challenging case of digitalis toxicity. Cardionerds, what is the mechanism of action of cardiac glycosides?   Cardiac Glycosides (such as digoxin, digitalis, and oubain), inhibit the myocardial Na/K ATPase pump. This leads to an increased concentration of intracellular sodium, which then drives the influx of calcium into cardiac myocytes via the Na/Ca exchanger. This increase in intracellular calcium leads to further calcium release from the sarcoplasmic reticulum making even more calcium available to bind to troponin, increasing contractility.  In addition to their effect on inotropy, cardiac glycosides increase vagal tone, reducing SA node activity and slowing conduction through the AV node by increasing the refractory period  2) The first published account of digitalis to treat heart failure dates back to the 18th century, when botanist and physician William Withering published “An account of the Foxglove and some of its medical uses with practical remarks on dropsy, and other diseases”. A lot has changed over the years; what are some of the uses of digoxin in the modern day?   The DIG trial (1997) demonstrated a reduction in hospitalizations in patients with HFrEF treated with digoxin. However, no impact on mortality was shown. A major limitation from randomized trials of digoxin is the lack of contemporary background HF treatment (e.g., ARNI, SGLT2i, MRA, Device Therapy). Thus, its role in modern HFrEF management is typically limited to reducing hospitalizations in patients with persistent NYHA Class III or IV symptoms despite maximally tolerated guideline-directed medical therapy  Digoxin can also be used for acute or chronic rate control in atrial fibrillation, and may be particularly useful in patients with RVR refractory to beta blockers/calcium channel blockers or in those patients who cannot tolerate these agents due to hypotension. Notably, data from the ARISTOTLE trial (2018) showed a significant mortality increase was seen in patients with a digoxin level ≥1.2 ng/ml, while no increase in mortality was seen with levels <0.9 ng/ml.   Recent data from the small, randomized RATE-AF trial showed no difference in quality of life and similar heart rate control in older patients with permanent atrial fibrillation and heart failure symptoms. Thus, while the therapeutic window may be limited, there remains a role for digoxin in the treatment of HFrEF, Afib, or both.  3) While digoxin can

CardioNerds (Carine Hamo, Amit Goyal, and Daniel Ambinder) discuss the obesity epidemic and how it relates to the cardiovascular system with Dr. Chiadi Ndumele, cardiologist and epidemiologist at The Johns Hopkins Hospital and chairs the obesity subcommittee of the American Heart Association (AHA). They cover obesity definitions, epidemiology, strengths and limitations of different biometrics, including BMI, impact on myocardial structure and function, and current pharmacologic & surgical options for weight loss. They also discuss the practical approach to addressing obesity with patients. This episode was produced by Dr. Carine Hamo. Show notes & references by Dr. Daniel Ambinder.

Show notes 1. What is obesity and how do we define it at the personal and population level? Obesity is when there is an excess and often dysfunctional adipose tissue that contributes to morbidity and to premature mortality The metric used to define obesity is Body Mass Index (BMI), defined as a person’s weight in kilograms divided by the square of the person’s height in meters (kg/m2) See WHO BMI classification below 2. What is the current epidemiology of obesity and are there certain populations that are affected more than others? Rates of obesity are climbing. Currently, around 70% of the population meets criteria for being either overweight or obese and ~40% are at the level of obesity. Minorities such as African Americans, Native Americans, and Latinos have higher rates of obesity. Higher rates of obesity are also seen in groups with lower socioeconomic status. Certain populations, such as Southeast Asians, tend to develop severe metabolic consequences of obesity such as insulin resistance and cardiovascular consequences with less excess weight than other populations. Adult weight is very important but weight history (long standing obesity) plays a role as well when it comes to cardiovascular risk associated with obesity. 3. Currently the WHO classifies obesity based on BMI. What are the limitations to using BMI as a measure of obesity? Are their benefits to measuring waist circumference instead? BMI is a far from a perfect measure but it correlates nicely at the population level with cardiovascular events and premature mortality BMI is more accessible than a direct quantitative or functional measure of adipose tissue A major limitation of BMI is that it does not reflect body composition. Body composition is very important in understanding risk associated with obesity. For example, football players may fall into the category of grade 1 obesity if just using BMI to classify their weight status. Waist circumference (WC) is a good way of getting a sense of body composition. Abdominal obesity is most closely linked to insulin resistance and various metabolic consequences such as diabetes, hypertension, and inflammation. This is why WC is incorporated into the metabolic syndrome construct. Adding WC measurements to the BMI measurements, particularly for individuals in the overweight and grade 1 obesity group (BMI 25-29.9, and 30-34.9) provides significant prognostic information about the development of cardiovascular disease. 4. How do obesity and metabolic syndrome impact myocardial structure and function? How does obesity and increased adiposity fit into the larger scheme of metabolic risk and metabolic syndrome? Obesity is independently associated with myocardial remodeling and with increased heart failure risk. This contrasts with coronary heart disease (CAD) and stroke. For CAD and stroke, most associations with obesity are largely mediated by diabetes, hypertension and dyslipidemia. However, in heart failure, there is a strong unexplained association that remains after you consider those associated conditions. The independent association of obesity with heart failure pertains almost exclusively to heart failure with preserved ejection fraction (HFpEF) and not heart failure with reduced ejection fraction (HFrEF). The mechanism for this independent association is not well understood and is an area of active research. In mice that are predisposed to obesity have several inflammatory processes that occur locally in the myocardium and systemically that likely contribute to cardiac risk. At the local level, lipotoxicity occurs within the myocardium as it does in nonalcoholic fatty liver disease. At the systemic level, adipose tissue releases adipokines and cytokines that are linked to myocardial damage, injury, and fibrosis. There is a spectrum of metabolic risk among individuals with excess weight. And when obesity is associated with metabolic syndrome in individuals, the risk for cardiovascular disease markedly rises. 4. What are some core tenants of addressing obesity when working with patients when

CardioNerds (Amit Goyal and Daniel Ambinder) discuss diabetes mellitus with Dr. Dennis Bruemmer. This is a must-listen for anyone engaged in the case of the cardiovascular patient. Given the alarming obesity epidemic, we anticipate a rising worldwide tide of diabetes mellitus and ensuing cardiovascular disease. Here we discuss the epidemiology and approach to diabetes management, with emphasis on what CardioNerds need to know. Dr. Bruemmer is board-certified in both cardiology and endocrinology, and is the director of the Center for Cardiometabolic Health in the section of Preventive Cardiology and Rehabilitation at the Cleveland Clinic.

Show notes Why should CardioNerds pay attention to diabetes mellitus (DM)?  As a cardiovascular risk equivalent, DM is a key CVD risk factor, associated with a 2-4 fold increased risk. 70% of ACS patients have DM.  Cardiologists will see more patient with DM given the rising prevalence of obesity, subsequent diabetes and ensuing CVD.   Only 6% of patients with DM and cardiovascular disease (CVD) get appropriate care for DM and CVD.  Historically, hypoglycemic agents improved microvascular outcomes (retinopathy, nephropathy, neuropathy), but not macrovascular outcomes (MI, CVA, PAD). However, this has changed with the advent of mandatory cardiovascular safety trials with positive data for GLP1 agonists and SGLT2 inhibitors!  There aren’t enough endocrinologists! They only see ~5% of DM patients. In 2012 the US generated 280 endocrinologists versus  100 million patient with DM or pre-DM. Primary care physicians are key allies in the care of these patients.   So as CardioNerds, let’s get over this therapeutic inertia and take ownership of our patients’ DM as we already do for their HTN and HLD; in collaboration with a multidisciplinary team including the PCP, dietician, pharmacist, DM educators, +/- behavioral therapist, +/- endocrinologist, +/- metabolic surgeon.  What is your global approach to the patient with DM?  Optimize the non-DM CVD risk factors with lifestyle intervention and medical management: CVD risk factors are very common in patients with DM (sedentary lifestyle, unhealthy weight, HTN, HLD).  The Steno-2 Study (Gaede et al., NEJM 2008) showed that in patients with T2DM & microalbuminuria, intensive intervention with multiple drug combinations and behavioral modification was better with regards to: vascular complications, death from any cause, and death from CV causes.      Emphasize a healthy lifestyle –  use a patient-centered approach with motivational interviewing and shared decision making, provide education, set realistic goals, identify barriers (socioeconomic, etc), engage family and a multidisciplinary team (nutritionist, exercise physiologist), utilize behavioral interventions.  Pharmacologic intervention – medical weight loss for BMI > 27 and DM (enjoy upcoming Ndumele episode), anti-HTN (enjoy upcoming Laffin episode), and anti-HLD (enjoy the Navar-Shah episode). NOTE that statins have been shown to have a small effect on increasing incident or worsening DM, but the effect size is small and overcome by the benefit in whom statins are indicated.                 Treat the Hyperglycemia itself! Let’s discuss this deeper…  What is your approach to non-insulin DM management?  First-line agents: US guidelines: in addition to lifestyle intervention, start with metformin as the first line agent.  European guidelines: now give preference to GLP1 agonists and SGLT2 inhibitors in patients with or at risk for cardiovascular disease.  Sulfonylureas: increase pancreatic insulin secretion. Dr. Bruemmer feels they obsolete for the preventive cardiologist from the standpoints of safety, efficacy, and cardiovascular disease. There is no efficacy data past 4 years and no cardiovascular benefit. In contrast data suggests increase all-cause mortality and possibly MACE events. Low cost may make these more affordable for some patients.   Thiazolidinediones (aka: “glitazones”): increase insulin sensitivity, the primary defect in T2DM. Rosiglitazone is discouraged due to adverse cardiovascular outcomes. Pioglitazone has better data, especially in those who’ve had a stroke or TIA (IRIS Trial, NEJM 2016). They may have a role in those for whom other classes are contraindicated or cost-prohibitive.   DPP4 Inhibitors: increase incretin levels (GLP-1 and GIP) which inhibit glucagon release, increase insulin secretion, and delay gastric emptying. They do not cause hypoglycemia or weight gain. These have a

Show notes – Aspirin, Vitamin D, Calcium & Omega 3 Fatty Acids Supplementation What is the role of aspirin for primary ASCVD prevention?  The Conundrum: ASCVD event rates are much lower in the primary prevention than in the secondary prevention population, BUT the bleeding rates are comparable. So in the primary prevention patients, the bleeding risk is just as high, but the propensity for benefit is lower.  The Question: Does low dose aspirin have a place in the primary prevention of ASCVD events.  The Data:  ARRIVE Trial: in moderate risk nondiabetic patients without prior ASCVD events, there was no different in the composite ASCVD end point, but there was an increased risk of bleeding (mostly mild GI bleeding). Thus, in the moderate risk patients –> primary prevention aspirin has an unfavorable risk-benefit profile. The benefit in a higher risk (>10-20% estimated 10-yr risk) remains unclear.   ASCEND Trial: In men and women age ≥ 40yrs with diabetes without prior ASCVD events, there was a modest benefit (NNT = 59 patients for 10 years to prevent 1 major ASCVD event) counterbalanced by a similar magnitude of harm (NNH = 77 patients for 10 years to cause 1 major bleeding event). Thus, in adults with diabetes –> primary prevention aspirin had a neutral risk-benefit profile.  ASPREE Trial: in elderly patients (≥ 70 years; ≥ 65 years for Hispanic or Black patients) without prior ASCVD events, there was no difference in ASCVD events but there was a significant increase in bleeding events (NNH = 42 patients for 10 years to cause 1 major bleeding event). The trial was stopped early due to futility. Interestingly, there was higher all-cause mortality driven primarily by cancer. Importantly, patients had to have a life expectancy longer than 5 years and those with dementia, substantial physical disability, or high estimated bleeding risk were excluded. Thus, in elderly patients –> primary prevention aspirin led to overall harm.   The Recommendations:  There was insufficient evidence to recommend a specific risk threshold for starting primary prevention aspirin. This may be due to more widespread contemporary prevention strategies like lifestyle management, tobacco cessation, statin use, better blood pressure control, etc.   Individualize the decision based on the totality of evidence for an individual’s risk of ASCVD events versus bleeding events. Notably, those with higher ASCVD risk generally also have a higher bleeding risk.            Class IIB: Low-dose aspirin (75-100 mg orally daily) might be considered for the primary prevention of ASCVD among select adults 40 to 70 years of age who are at higher ASCVD risk but not at increased bleeding risk.  There may be a role for primary prevention aspirin in select adults with a high estimated ASCVD risk and low bleeding risk.  CAC score ≥ 100 may help identify those might benefit from primary prevention aspirin.            As always, shared decision making remains           crucial.  Class III: Low-dose aspirin (75-100 mg orally daily) should not be administered on a routine basis for the primary prevention of ASCVD among adults >70 years of age.  Class III: Low-dose aspirin (75-100 mg orally daily) should not be administered for the primary prevention of ASCVD among adults of any age who are at increased risk of bleeding.  What is the role of Vitamin D supplementation in preventing cardiovascular disease?             The Conundrum: Low levels of Vit D is associated with increased risk of CV outcomes including myocardial infarction, stroke, heart failure, atrial fibrillation, and more. But while low Vit D seems to be a marker for bad outcomes, correlation ≠ causation. Notably, this correlation was not confirmed by Mendelian randomi

Surgical repair of LA & Esophagus Episode Teaching The CardioNerds 5! – 5 major takeaways from the #CNCR case What is a pulmonary vein isolation? What are the most common complications? When is catheter ablation indicated? The majority of Afib triggers come from areas where the pulmonary veins attach to the left atrium. Approximately 15-20% of patients undergoing ablation will have non-pulmonary vein triggers. Guided by this anatomic and pathophysiologic underpinning, electrical isolation and ablation of these areas helps prevent propagation of the Afib impulses. The most effective method for pulmonary vein isolation (PVI) is ablation of the PV antrum, areas located near the PV ostia, using an oval mapping catheter to confirm ablation of electrical activity from the PV ostia. Vascular access complications (e.g. hematoma, pseudoaneurysm) are the most common complications following PVI and occur in approximately 1-4% (KD: I think complication rate is lower in studies I’ve reviewed) cases. Most other complications occur in less than 1% of cases and include cardiac tamponade/perforation, TIA/stroke, PV stenosis, pneumonia, phrenic nerve palsy, gastric motility disorders, atrial-esophageal fistula, and death. There is some growing evidence that catheter ablation may be superior to medical management alone in certain symptomatic populations (e.g., HFrEF). However, in the recent CABANA trial, catheter ablation did not significantly reduce death, disabling stroke, or serious bleeding compa

On exam he was warm and well perfused, though hypotensive, tachycardic with an irregular rhythm, and had an elevated JVP. ECG showed AF with RVR without evidence of acute MI, and troponin was negative. TTE revealed a reduced LVEF and WMA in the inferolateral walls with akinesis of the basal mid septum; additionally, two large extracardiac structures were noted, one with heterogenous echotexture in the AV groove, and a second with an echolucent interior adjacent to the RA. The patient underwent coronary angiography, showing a dilated and calcified proximal LAD with high grade stenosis adjacent to the first septal perforator, a ectatic LCX that supplied left to right collaterals, and a giant RCA aneurysm with TIMI 0 flow distally. CCTA confirmed these findings, showing thrombosed aneurysms of the LAD, LCX, and RCA. Interventional cardiology and cardiac surgery both evaluated the patient’s case, and determined that he was not a candidate for intervention. He was ultimately diuresed to euvolemia with significant improvement in symptoms, and plans to follow-up as an outpatient for heart transplant evaluation. Case Media A B C D Click to Enlarge A. CXRB.

CT chest demonstrating giant aneurysm TTE Coronary Angiography Episode Schematics & Teaching The CardioNerds 5! – 5 major takeaways from the #CNCR case 1) This case featured a patient with a giant coronary aneurysm – how are coronary artery aneurysms defined and classified?   Coronary artery aneurysms (CAA) are defined as a focal dilation of a coronary segment at least 1.5x the adjacent normal segment. Contrast this with coronary artery ectasia, which refers to a diffuse, as opposed to focal, coronary dilation.   CAA morphology can be classified as either saccular (transverse > longitudinal diameter) or fusiform (transverse < longitudinal diameter).  Giant CAA’s are >20mm in diameter.  Aortocoronary saphenous vein graft aneurysms have distinct characteristics and natural history compared to native coronary aneurysms. These aneurysms tend to present late (e.g., > 10 years following CABG) and tend to be larger than native CAA.  IVUS can help differentiate between a true aneurysm with preserved integrity of all 3 vessel layers (intima, media, and adventitia) and a pseudoaneurysm with loss of wall integrity and damage to the adventitia.  2) Now that we have the language to define and classify coronary artery aneurysms, what are some causes these lesions?   Atherosclerosis: lipid deposition, focal calcification, and fibrosis can weaken the vessel wall and predispose to subsequent coronary artery dilation. Up to 50% of CAAs are linked to arteriosclerosis.   Autoimmune/inflammatory processes: Lupus and systemic vasculitis, such as Kawasaki’s disease and Takayasu arteritis, can all lead to CAAs. Vasculitic CAAs usually affect more than one artery.   Connective Tissue Disease: Marfan’s syndrome and Ehlers-Danlos disease, for instance, are characterized by deficiencies in vessel wall integrity, leading to CAAs.  Dynamic Wall Stress: Episodic hypertension and vasoconstriction, such as that seen in frequent cocaine use, can lead to wall stress, endothelial damage, and coronary artery aneurysms.   Direct Vessel Wall Injury: Intracoronary interventions, such as angioplasty, stent delivery, and brachytherapy, can cause shear wall stress that leads to CAAs.   Infectious Causes: Direct vessel wall invasion or immune co

What are the most common etiologies? Based on the 2015 ESC guidelines on pericardial disease, acute pericarditis is diagnosed when at least two of the following four criteria are present: Chest pain characteristic of pericarditis Acute onset, improves with leaning forward, pleuritic Pericardial rub EKG changes consistent with pericarditis PR depressions, ST segment elevation though depending on time course these can normalize or become T wave inversions New or worsening pericardial effusion Etiology can vary by geography. In most developed countries, viruses are thought to be the most common cause, though even when a viral cause is suspected, the majority of cases end up being idiopathic. Other etiologies include bacterial (TB is the most common cause of pericarditis in developing countries), autoimmune, hypothyroidism, malignancy, r

The CardioNerds 5! – 5 major takeaways from the #CNCR case What’s the differential for LVH and what findings are more suggestive of HCM? Causes for LVH can be either pathological or physiological. Pathological causes include infiltrative diseases like hypertrophic cardiomyopathy (HCM), Amyloidosis, or Fabry disease and inflammatory diseases like myocarditis. Physiological causes are due to remodeling from increased cardiac output or workload like in athletic heart or from a high afterload state such as in aortic stenosis and hypertension. In hypertension, AS, and athletic heart, LV hypertrophy is more commonly concentric and rarely exceeds 15mm. In HCM, LV hypertrophy is more commonly asymmetric (basal anteroseptum > posterior wall), often >15mm, and typically involves the basal ventricular septum. Differentiating pathologic versus physiologic causes of LVH can typically be done from a detailed history and exam (e.g., evidence of hypertrophy out of proportion to pressure overload, multisystem involvement). Cardiac MRI can be used to differentiate between HCM and other phenocopies. In HCM, LGE is usually seen at the insertion point of the LV and RV or the most hypertrophied myocardial regions whereas in amyloidosis, endomyocardial LGE is more characteristic. What are some characteristic exam findings seen in HoCM? Systolic murmur at the left sternal border can be heard in patients with obstructive HCM (HoCM). The murmur is a result of LVOT obstruction due to systolic anterior motion (SAM) of the mitral valve and LV basal septal hypertrophy. Maneuvers that decrease preload, such as Valsalva or going from a sitting to upright position, will enhance the obstruction and increase the intensity of murmur. Maneuvers that increase the preload or afterload, such as squatting or handgrip, will decrease the intensity of murmur. Additionally, mitral valve pathology – whether a primary valve process or secondary to SAM/ abnormal

EMS arrived after three minutes of bystander CPR. An AED indicated the patient had suffered a VF arrest. ROSC was achieved after 1 round of Epi and 1 shock delivered. He was intubated and started on targeted temperature management protocol. Home medications were  notable for digoxin 0.25mg daily, sotalol 120mg BID, and warfarin 5mg daily. Initial labs were notable for Na 127, K 5.4, Cr 1.0 (unknown baseline), INR 4.5, Lactate 4.6, Troponin-I 0.532, VBG 7.06/61, and random Digoxin level 2.7. EKG showed AV sequential pacing at a rate of 70 bpm. QTc prolonged at 571ms. No ischemic ST changes. Device interrogation showed sustained VT for 5 minutes prior to external shock. No internal shock was delivered. He was initially stabilized and his acidosis and hyperkalemia were corrected. Course was complicated by hemoptysis due to alveolar hemorrhagic and he was given concentrated prothrombin complex to reverse his coagulopathy. He eventually stabilized, and a formal TTE was obtained which showed a hypoplastic RV, single dilated LV with an akinetic posterior wall and hypokinetic lateral wall, all similar to his prior TTE in 2019. No obstruction noted at the IVC/Fontan anastomotic site. Coronary angiogram performed after his kidney function improved also did not show any significant obstructions or coronary anomalies. After multidisciplinary discussion, his VF arrest was attributed to a combination of prior ventricular fibrosis/scar, suspected digoxin toxicity, sotalol, dehydration, and renal failure. He had a subcutaneous ICD lead placed and was ultimately discharged home.  Case Media A B Click to Enlarge A. CXRB. ECG Episode Schematics & Teaching The CardioNerds 5! – 5 major takeaways from the #CNCR case What’s Transposition of the Great Arteries (TGA)?  TGA is defined by a nontraditional ventricle-arterial relationship so that the aorta arises from the morphological RV and the pulmonary artery (PA) arises from the morphological LV  There are two types of TGA, L or levo and D or dextro.  D (rightward)-TGA: Systemic venous return flows into RA -> RV -> delivered to systemic circulation via Aorta, bypassing the lungs. The pulmonary veins flow into the LA -> LV-> delivered to the pulmonary circulation via the PA. The result is two parallel systems that fail to deliver oxygenated blood to the systemic circulation. This is not compatible with life unless another defect such as ASD, VSD, or PDA is present (or created) to allow mixing of deoxygenated and oxygenated blood. Patients with D-TGA usually require arterial switch procedures within 1 month of life. A simplified way to understand this is to say that the great vessels are malpositioned, leaving patients

Past medical history included anxiety. Initial vitals and physical exam were unremarkable. Labs were notable for an elevated troponin T of 360 ng/L and a low TSH of 0.02 mIU/L with an elevated free T4 of 5.1 ng/dL. EKG demonstrated lateral and inferior ST depressions. TTE demonstrated a normal LVEF of 58% with a subtle anterolateral wall motion abnormality. Given her lack of conventional risk factors for CAD, resolution of her chest pain, and downtrending troponin, coronary CTA was obtained next which did not show any CAD but demonstrated an anomalous left main coronary artery (LMCA) arising from the main pulmonary artery with evidence of left to right shunting from the left main into the PA and extensive coronary and bronchial collateralization. The anterior wall hypokinesis was also seen on CT, consistent with ischemia due to myocardial steal phenomenon. Given the abnormal thyroid function tests, thyroid US was also obtained which showed patchy heterogeneity consistent with thyroiditis. Ultimately, the patient was diagnosed with ALCAPA and her chest pain was attributed to steal phenomenon due to hyperthyroidism and increased cardiac demand. She was treated with long-acting nitrates and beta-blocker with resolution of symptoms and was referred to cardiac surgery on discharge.   After a multidisciplinary discussion involving the cardiac surgery team, patient underwent ligation of LMCA with SVG bypass to LAD. One month after operation, she developed palpitations and chest pain during exertion and was taken to the hospital. Labs showed an elevated hs-troponin T of 711 ng/L and she was treated for type 1 NSTEMI with aspirin, heparin drip, and statin. Repeat TTE demonstrated normal LVEF and lack of WMA. LHC showed occlusion of SVG graft and possible thrombus in LAD near the site of graft anastomosis. RCA was large and patent, providing adequate collaterals to the left coronary system. Ultimately, PCI was deferred and medical management was pursued because she had adequate collaterals from right coronary system. She was treated with DAPT, beta-blocker, and atorvastatin and has been doing well since.   Case Media A B C D E F Click to Enlarge A. CXRB. ECG C. Follow up ECGD-F.

This complex process heavily depends on the proliferation and migration of cells that originate outside the heart at the sinus venosus and then differentiate into endothelial cells, vascular smooth muscle cells, and fibroblasts. Proper migration of these cells to aorta, creating the coronary ostia, depend heavily on expression of growth factors like FGF-2, PDGF, and VEGF.   Anomalous origin of a coronary artery from the aorta or from the pulmonary artery have a common defect: the cells of the capillary plexus surrounding the aorta and pulmonary artery fail to reach and/or penetrate the normal sites of developing aorta. This can be caused by different mutations affecting the growth factor signaling pathways.     What is ALCAPA?  ALCAPA stands for anomalous left coronary artery (LCA) origin from the pulmonary artery. There’s also ARCAPA which is anomalous RCA origin from the pulmonary artery.   It occurs at an incidence of 1 in 300,000 live births or 0.25 to 0.5% of all congenital heart disease. It is difficulty to diagnose during infancy as it presents similarly to other more common pediatric

He was diagnosed with an idiopathic TAAA at age 30 after he was noted to have an incidental murmur. Over the next few years, his aortic root increased to over 7 cm with severe AR, LV dilation, and reduced LVEF of 45%. He underwent bioprosthetic aortic valve replacement and root repair with a Medtronic freestyle porcine aortic root with subsequent recovery of his  LVEF to 50% and improved LV dilation. Thereafter, he was doing well until he reported a flu like illness 3 weeks prior to presentation with reported fever up to 101.3 F and associated myalgias. He denied any sick contacts or recent travel and was adherent to his HIV regiment. On the day of presentation, he was walking his dogs when he developed acute onset lightheadedness with presyncope. On presentation, he had a low grade fever, tachycardia, tachypnea, and hypoxia. On exam, cardiac exam was notable for loud blowing diastolic murmur, non-distended JVP, decreased breath sounds, warm extremities with bounding pulses and without edema. There were no stigmata of endocarditis. Labs revealed elevated cardiac and inflammatory biomarkers. Blood cultures were initially NGTD. CXR corroborated the exam with bilateral interstitial and airspace opacification with effusions. TTE showed LVEF 35% with global hypokinesis, dilated LV with LVEDD 7.5 cm, mild RV systolic dysfunction, severe AR with holo-diastolic flow reversal in the abdominal aorta, no prosthetic stenosis, and aortic root 31 mm. TEE showed a well-seated AVR with leaflet thickening and several echodensities. CT surgery deemed patient to be high risk for the OR. After a few days, patient required intubation for increased work of breathing and acute decompensation requiring vasoactive infusions. After multidisciplinary discussions, the patient ultimately underwent ViV TAVR with successful placement of a 29 mm Edwards Sapien 3 valve. That day, he was weaned off pressors, and subsequently extubated. Infectious workup remained negative thereby resulting in a final diagnosis of prosthetic aortic valve culture-negative endocarditis vs sterile prosthetic valve deterioration. He was discharged on intravenous empiric antibiotics and was doing well in clinic 2 months later.   Case Media A B C D E F Click to Enlarge A.

Cardiology was consulted for pre-operative management. When obtaining a cardiac history, she reported rare, intermittent, and non-anginal chest pain. She had no current chest pain or dyspnea. On chart review, she had multiple presentations over the past 3 years for various complaints – some were chest pain – during which she was found to have elevated troponin I values. Most of the elevations were in the 0.5 to 1 ng/mL range, but one time, her peak troponin was 32 ng/mL. At one of those presentations, she had a TTE that showed septal wall motion abnormalities. She underwent coronary angiography on two occasions, which both showed proximal and mid-LAD calcifications, but no significant stenosis and she was managed medically.   At the current presentation, her vitals were within normal limits and her exam did not show any cardiopulmonary abnormalities. Labs were notable for troponin I of 10 ng/mL but CK-MB was normal. Interestingly, alkaline phosphatase was 3 times the upper limit of normal, and rheumatoid factor was 1156 IU/mL compared to 70 previously (normal range 0-20 IU/mL). EKG was without ischemic changes. TTE showed no wall motion abnormalities, normal LVEF, and no significant valvular disease. Cardiac catherization was deferred, and the patient was not interested in cardiac MRI. Due to an incongruent troponin elevation with the clinical presentation, there was concern for interference with the troponin assay due to the elevated rheumatoid factor and alkaline phosphatase levels. Upon further investigation, dilution of the troponin yielded results lower than factor of dilution or undetectable results. Mayo testing of the sample showed troponin-T of 0.024 ng/mL (normal < 0.01 ng/mL), and troponin I of 0.02 ng/mL (normal < 0.04 ng/mL). Although there were still some aspects of her previous presentations including rising troponin pattern and previous wall motion abnormalities that are unexplained at this time, her troponin elevation at this presentation was attributed to assay interference.   Case Media A B C Click to Enlarge A.

The CardioNerds 5! – 5 major takeaways from the #CNCR case What is the universal definition of myocardial infarction?   ·       As per the current 4th universal definition, myocardial infarction is defined as an elevation in cardiac troponin (cTn) above the 99th percentile in high sensitivity assays in the setting of acute myocardial ischemia. It is considered acute if there is a characteristic rise/fall pattern in cTn.   ·       A type 1 event is a spontaneous MI related to ischemia as a result of a primary coronary event (e.g., plaque erosion or rupture, dissection). The definition requires the above biomarker threshold with at least one of the following as evidence of ischemia: symptoms of MI, new ischemic EGG changes including development of pathological Q waves, new imaging evidence of loss of viable myocardium, or identification of thrombosis by intracoronary imaging.  Unstable angina (UA) occurs in patients with symptoms suggestive of acute myocardial infarction but without biomarker elevation.  ·       Criteria for type 2 MI includes the biomarker definition above with evidence of ischemia seconda

Pre and post MitraClip left atrial pressure Episode Teaching The CardioNerds 5! – 5 major takeaways from the #CNCR case 1. What is Comprehensive Disease Modifying Therapy in HFrEF? Comprehensive disease modifying therapy for heart failure with reduced ejection fraction (HFrEF) has become both more robust and better understood by practitioners inside and outside the cardiology community.  Comprehensive therapy is generally considered to consist of beta-blockade, mineralocorticoid receptor antagonist (MRA), sodium-glucose cotransporter-2 inhibitors (SGLT2i) and angiotensin receptor neprilysin inhibitor (ARNI), with ARNI being the preferred agent over angiotensin converting enzyme inhibitor (ACEi) or angiotensin II receptor blocker (ARB).  Despite a greater understanding of HFrEF therapy by the medical community, significant gaps remain with recent data showing few patients on concomitant beta blockade, MRA, SGLT2i and ACE/ARB/ARNI, and even fewer at target doses. Compared to ACE, BB, and MRA alone, comprehensive therapy with MRA, BB, SGLT2i and ARNI could add an additional 6 years for middle-aged patients. 2. What role does Mitral Valve Disease have in Heart Failure Exacerbations? For patients that remain symptomatic or with repeated hospitalizations for decompensated heart failure despite comprehensive therapy, it is important to look for additional pathology contributing to heart failure exacerbations.  Mitral valve disease is one such etiology, particular secondary mitral valve regurgitation (MR) which can be seen in heart failure due to changes in left ventricular anatomy.  Severe MR is associated with worsening left ventricular function and heart failure. For some time, however, it was an open question if functional MR was secondary to heart failure or an independent cause of heart failure exacerbations. Recent major trials suggest severe MR may act independently to worsen or lead to more frequent heart failure exacerbations. 3. How Do we Assess Mitral Valve Function in Heart Failure? MR is primarily quantified by echocardiography, which allows for close observation of regurgitant flow. Once a diagnosis of secondary MR has been established by evaluating mitral valve morphology and leaflet motion (e.g., Carpentier Classification), there are several parameters including objective quantification of MR hemod

She was diagnosed with NET after presenting with a small bowel obstruction (SBO) several years prior. At the time, she was found to have liver and pulmonary metastasis with MR enterography showing thickening of the terminal ileum. Ileocecetomy and biopsy of the liver lesions confirmed metastatic NET. Despite treatment with octreotide and everolimus, follow up CT showed progression of liver lesions and she was eventually started on telotristat and enrolled in a clinical trial. On presentation, she was not tachycardiac, hypotensive or requiring oxygen supplementation (KD: Correct?). On exam, she demonstrated elevated JVP with a positive hepato-jugular reflex and a 3/6 holosytolic murmur loudest at the LLSB that increased with inspiration. Lab work revealed urinary 5-HIAA was 212 (nl < 6mg/24 hours). TTE showed moderately dilated RV and severely dilated RA. Furthermore, there was a thickened, calcified and retracted TV with severe TR which was consistent with carcinoid heart disease. She was treated with diuretics and was continued on systemic therapies to help achieve control of her NET before surgical intervention for her valvular disease was considered.

The majority of patients with carcinoid syndrome have metastases to the liver and the vasoactive substances (e.g., 5-hydroxytryptamine [5-HT]) reach the systemic circulation via the hepatic vein bypassing degradation in the liver.   Similarly, cardiac involvement occurs after metastasis to the liver and exposure of the heart to vasoactive substances. Generally, symptoms are limited to the right heart as the lungs clear carcinoid-related substances. Left-sided involvement may occur, however, in a patient with carcinoid heart disease and an intracardiac right to left shunt is present.   In addition to the symptoms of carcinoid syndrome, patients with carcinoid heart disease including severe dyspnea, fatigue, and signs and symptoms of right heart failure (e.g., ascites, peripheral edema).    The patient was

The CardioNerds 5! – 5 major takeaways from the #CNCR case What is Ehlers-Danlos Syndrome?   Ehlers-Danlos Syndrome (EDS) is a clinically and genetically heterogenous group of heritable connective tissue disorders due to altered collagen metabolism. The inheritance pattern is variable, but is mostly autosomal dominant, with a range of mechanisms including deficiency of collagen-processing enzymes, mutant collagen chains, and haploinsufficiency.    Although the syndrome has varying and overlapping clinical manifestations based on subtype (per the 2017 International ED Consortium there are 17 subtypes) it is largely characterized by hyperextensibility of the skin, hypermobility of joints, atrophic scarring, and tissue fragility. The cardiovascular system is involved in the vascular and cardio-valvular subtypes.  The incidence is estimated to be 1 in 2500 to 5000, however this is likely an underestimation since mild presentations may not be clinically diagnosed nor sent for genetic testing.    The differential diagnosis for suspected EDS includes osteogenesis imperfecta, Marfan syndrome, and Loeys-Dietz syndrome. Those with joint symptoms may be incorrectly diagnosed with fibromyalgia, chronic fatigue syndrome etc.    What is vascular EDS?   There are many subtypes of EDS. Type IV or vascular EDS (vEDS) is an autosomal dominant disorder that affects Type III procollagen protein synthesis. The incidence is rare – 1 in 50,000 to 250,000 people and is ~5% of all EDS cases.    It is commonly caused by a defect in the COL3A1 gene, most of which are single base substitutions, but more than 700 different mutations have been identified. Missense mutations at the C-terminal end of the molecule results in a more severe form of the disease.  Feared vascular manifestations include arterial dissection, rupture, and aneurysm formation. Death is most frequently secondary to complications from arterial dissection or hollow organ rupture. 70% of patients experience a first major event by age 20. Note, surgical repair of a ruptured aneurysm or dissection can be complicated by poor wound healing or hemorrhage because tissue in Ehlers-Danlos is friable.  In this subtype, the usual manifestations of joint hypermobility and skin hyperextensibility may not be as apparent.  The vascular type has the worst prognosis with median expectancy between 40-50 years of age.   How is vEDS diagnosed?   Vascular EDS should be considered in anyone with unexplained arterial or hollow viscus rupture, commonly the sigmoid colon, especially at a young age.  Diagnosis is confirmed by either finding of structurally abnormal type III procollagen in a culture of dermal fibroblasts or COL3A1 gene mutation. Clinical criteria can aid in the decision to pursue testing.    Molecular testing is recommended when meeting one or more major clinical criteria or several minor criteria. Major criteria include family history of vEDS, unexplained arterial rupture at young age, spontaneous intestinal  perforation (in absence of risk factors), uterine rupture during pregnancy and labor, or carotid-cavernous sinus fistula formation.    Some minor criteria include bruising without trauma (especially in unusual locations), spontaneous pneumothorax, tendon/muscle rupture, gingival recession, early onset varicose veins, and characteristic facial appearance amongst other criteria.

He was tachycardic and hypotensive. Labs were notable for Hgb 8.1 (baseline of 10.2), INR 1.3, lactate 4.2, and ferritin 4660. He was started on IV PPI and octreotide. Course was complicated initially by Afib with RVR with hypotension. Subsequently, the patient developed unstable VT requiring CPR. Post-code EKG showed inferolateral ST elevations. Troponin-I rose from 19 to 225 and his pressor requirement continued to increase despite resolution of his GIB. TTE showed LVEF 42% with new inferolateral wall motion abnormalities, normal RV systolic function, severe mitral regurgitation, and small pericardial effusion. After treatment of his GIB by IR and GI, he underwent an urgent LHC which showed 30% stenosis in proximal LAD, 70% in LADD2, and 95% in distal RCA. Coronary spasm was noted in all vessels. Intracoronary nitroglycerin and nicardipine were administered with significant improvement in spasm and resolution of STE on EKG. Vasopressors were quickly weaned off after. He was eventually stabilized, extubated, and started on an oral nitrate and calcium channel blocker. Repeat TTE showed normalized systolic function without any wall motion abnormalities.   Case Media A B Click to Enlarge A. Baseline ECG – atrial fibrillationB.

Initially, hemochromatosis leads to diastolic dysfunction and arrhythmias. In later stages, it can lead to dilated cardiomyopathy.   Diagnosis of iron overload is established by elevated transferrin saturation (>55%) and elevated serum ferritin (>300 ng/mL). Genetic testing for mutations in the HFE gene should be pursued.  Cardiac MRI with measurement of T2* relaxation times is the diagnostic test of choice as it can both detect and quantify myocardial iron overload. The iron content in the myocardial tissue is inversely proportional to the time constant of decay for relaxation time. Thus the higher the iron content, the shorter T2* relaxation time.   What are the causes of ST-segment elevation on EKG besides acute plaque rupture or vasospasm?  Pericarditis: in acute pericarditis, ST elevation can be seen diffusely in all leads, with PR segment depression (except lead aVR +/- V1). The diffuse ST elevations are due to involvement of subepicardial layer of the ventricular wall. The PR depressions are due to involvement of the subepicardial layer of the atrial wall.   Stress CM: The ECG findings of stress cardiomyopathy may be indistinguishable from STEMI secondary to acute plaque rupture.&#16

She had no family history of arrythmias, SCD, or prior syncope. Her heart rate was 170 bpm and EKG showed wide complex, regular tachycardia felt to be VT. She underwent synchronized cardioversion to sinus rhythm. Her baseline EKG showed sinus bradycardia with low voltage, incomplete RBBB, and ventricular ectopy. Labs were unrevealing, and social history was negative for toxic insults or illicit substance abuse. TTE showed preserved LVEF and normal valves, but RV was dilated with decreased systolic function. LHC was without obstructive coronary disease. She was diagnosed with ARVC and received an ICD for secondary prevention. She was discharged on sotalol for arrythmia management. Her genetic testing later returned positive for uncertain significance in the DSP gene and JUP gene, both commonly implicated in ARVC. She was followed in the outpatient setting for 5 years with no apparent shocks. Six years later, she presented with acute onset dizziness and palpitations similar to her initial presentation. EKG showed a wide complex tachycardia at 170 bpm treated with amiodarone and cardioversion. On ICD interrogation, she was found to have had several episodes of VT, but at a rates below the VT detection zone programmed in the ICD. Subsequent RHC showed significantly depressed cardiac index and RV dysfunction. She underwent successful inpatient VT ablation. She was then discharged home with plans for close follow up; however, 2 days later, she started feeling nauseous with fatigue and abdominal pain. She was sent straight to the nearest transplant-capable hospital where she was found to be in cardiogenic shock. She was admitted to ICU and started on inotropes. Due to refractory shock, she was cannulated for VA ECMO and successfully underwent cardiac transplantation two days later.   Case Media 1 2 3 Click to Enlarge A.

Clinical manifestations include RV dysfunction, ventricular arrhythmias, and sudden cardiac death (SCD).  This is a progressive disease that can affect the epicardium and/or mid-myocardium first and then move towards the sub-endocardium.   It affects approximately 1 in 5000 individuals and is an important cause of (SCD) in young patients. 50% of patients have a positive family history and it is thought to be inherit in an autosomal dominant fashion, however prevalence is underestimated due to incomplete penetrance. Interestingly, males are more affected than females possibly due to interaction of sex hormones with pathophysiology or historically different levels of participation in competitive sports among men and women.  The differential for ARVC should include Uhl’s anomaly, myocarditis, sarcoidosis, and Brugada syndrome among other considerations.  What genes are implicated and what is the pathophysiology?  While 20-30% of ARVC is due to non-desmosomal gene variants (e.g., desmin, Titin) and non-genetic causes, 40-50% is due to autosomal dominant gene mutations that encode desmosomal proteins.

TTE shows an EF of 62%, normal gradients across the mitral valve without mitral regurgitation, and a dilated IVC. She is admitted with a presumed diagnosis of decompensated heart failure, and started given IV furosemide. Her symptoms slightly improve though do not resolve, and her creatinine increases from 1.4 to 2.1.   In light of the unclear hemodynamic picture, a RHC is done, showing a RA pressure 9, RV pressure of 80/10, PAP 70/25 with mPAP 40, PCWP 30, SVR 872, CO 11 (by thermodilution), and CI 5.2. Notably, large V waves are noted on the RHC. Given concern for mitral regurgitation in the setting of large V waves, a TEE was pursued, which confirmed the lack of MR seen on TTE. Thus, her large V waves were felt to be due to stiff left atrial syndrome, and a cardiac CT showed a severely calcified “coconut left atrium”. Labwork revealed a profoundly low thiamine level (21, with LLN of 70), raising concern for wet beri beri syndrome.   The patient’s unifying diagnosis was indolent left atrial syndrome that was exacerbated by high outout heart failure due to Wet Beri Beri syndrome.

During LV systole (atrial diastole), the LA receives blood from the low-resistance pulmonary veins. Under normal conditions, the LA pressures initially fall (x-descent). Then, as the atrium fills from both RV contraction and passive filling from the pulmonary veins, there is a steady and modest rise in LA pressure (v-wave). In patients with decreased LA compliance, the V-wave may be accentuated.   In SLAS, left atrial compliance is significantly decreased, leading to very large v-waves that reflect the inability to accommodate LA filling and the steepened slope of the pressure-volume c

Her past medical history includes metastatic breast cancer s/p mastectomy, chemo/radiation, and hormonal therapy. Exam notable for tachycardia without hypoxia, muffled heart sounds, JVD with Kussmaul’s sign, and 1+ LE edema. The patient was sent to the ED for evaluation of possible pericardial effusion. CTA chest in ED did not demonstrate a PE, but did show bilateral pleural effusions, and a moderate pericardial effusion with evidence of metastatic disease extending into the mediastinum. TTE obtained showing normal LVEF, moderate pericardial effusion with thickened pericardium, and significant respirophasic tricuspid and mitral inflow variations. Pulsus paradoxus was manually checked and found to be 16 mmHg.  Due to concern for cardiac tamponade, she was taken to the cath lab for a RHC and pericardiocentesis. RHC prior to pericardiocentesis showed elevated left and ride sided filling pressures, blunted y decent in the RA, and equalization of diastolic pressures. Pericardiocentesis yielded 200 cc of bloody fluid with improvement, but continued elevation, in her L and R sided pressures. Blunted y decent did give way to a now rapid y descent concerning for constrictive pericarditis. She then underwent a cardiac MRI showing respirophasic septal motion suggestive of interventricular dependence and >1 cm thick pericardium with LGE c/w inflammation. Unfortunately, cytology of pericardial fluid was c/w a malignant effusion and despite treatment with a few months of anti-inflammatory therapy her symptoms did not improve. She then underwent a pericardial stripping with subsequent resolution of her symptoms. As her symptoms and hemodynamics were related to both the effusion and constriction, she was ultimately diagnosed with effusive constrictive pericarditis.  Case Media A B C D E F G H I J K L M N O Click to Enlarge A.

The CardioNerds 5! – 5 major takeaways from the #CNCR case What is cardiac tamponade, what causes it, and how does it lead to hypotension?  The pericardial cavity typically holds 50 cc of fluid, which acts as a lubricant for the beating heart. Accumulation of additional fluid in this space can increase intrapericardial pressure and cause compression of the cardiac chambers. Rapid accumulation of small amounts of fluid can lead to tamponade as the pericardium will not have time to expand. In instances of a slow accumulation, large volumes might accumulate before tamponade occurs as the pericardium will expand to accommodate

On exam, he was ill appearing, acutely distressed, and altered. He had a 3/6 mid systolic murmur loudest at L sternal border, JVP to 10 cm H2O and had crackles up to mid-lung fields. His extremities were cool to touch. Labs notable for Cr 1.5, High-Sensitivity Troponin-T up to 5756, and lactate 3.9. EKG showed incomplete RBBB, PVCs, and ST elevations in the inferior leads with depressions in lateral and precordial leads. Coronary Angiography showed mid-RCA occlusion with faint L to right collaterals. He underwent PCI with restoration of TIMI 3 flow. After PCI, he continued to be hypotensive requiring IABP and norepinephrine. PA catheter demonstrated (in mmHg): RA 26, RV 63/29 (31), 55/36 (44), PCWP 29, and CO 5 L/min, CI 2.2, and SVR 467. Shunt run of mixed venous O2 saturation showed: SVC 71%, RA 72%, RV 62%, PA 85% with oxygen step up in the R-sided circuit. Left ventriculogram then confirmed septal rupture with contrast extravasation from LV into RV. Due to worsening shock, he was stabilized on VA ECMO which was complicated by hemolysis and acute renal failure requiring CVVHD. On day 7 after presentation, he underwent surgery which revealed a large 6×6 cm ventricular septal defect on the posterior aspect of the septum and repaired with a large bovine pericardial path. He was eventually discharged after a prolonged stay and repeat TTE on follow up showed biventricular dysfunction and residual 1cm VSD.   Case Media A B C D Click to Enlarge A.

On arrival, he was hypothermic, in rapid atrial fibrillation with HR in the 130-150s, and an initial BP was not able to be obtained. He was tachypneic with labored breathing, lethargic, and cyanotic. Exam revealed markedly elevated JVP, cool extremities, and diminished breath sounds with bibasilar rales. Labs demonstrated leukocytosis, significantly elevated liver enzymes, troponin-I at 10.91, elevated NT-proBNP, and lactate at 6. ECG demonstrated tall, broad R-waves in V1-V4 with downsloping STD and upright T-waves concerning for a posterior infarct. He was immediately intubated, cardioverted into NSR, and started on vasopressors. Bedside echocardiogram demonstrated diffuse LV hypokinesis with akinesis of the inferolateral wall, LVEF 25-30%, and pericardial fluid with hyperechoic material adherent to the inferior wall as well as tamponade physiology. Chest CTA was negative for aortic dissection and confirmed hemopericardium. He was taken to the OR where he underwent a subxiphoid pericardial window. They found significant clot burden (both old and new), but no frank rupture. Adherent clot was not removed to prevent further hemodynamic compromise. Intraoperative TEE additionally demonstrated severe eccentric MR with partial posteromedial papillary muscle rupture. An IABP was placed and inotropic and vasoactive support was continued to temporize pending definitive therapy and the patient improved hemodynamically. Repeat TTE prior to surgery demonstrated a large apical and inferolateral pseudoaneurysm. Coronary angiogram revealed proximal occlusion of the LCx and diffuse three vessel coronary disease otherwise.

On presentation, he was normotensive and borderline tachycardic. Exam revealed elevated JVP, decreased breath sounds, and pitting edema.  Labs demonstrated leukocytosis, acute kidney injury, and elevated pro-BNP. TTE demonstrated LVEF 35%, apical akinesis, and grade III diastolic dysfunction (all similar to prior). He was initially diuresed and RHC/EMB was performed to evaluate for rejection. Early in his course, the patient unfortunately suffered a PEA arrest with ROSC was quickly achieved after 1 minute of CPR. He was intubated and cannulated for VA ECMO. EMB demonstrated ISHLT Grade 1R cellular rejection and he was ultimately listed for re-transplant. Shortly thereafter, the patient received an OHT. His pathology demonstrated intimal thickening of all his coronaries, consistent with coronary artery vasculopathy, felt to be the major contributor to his presentation.   Case Media ECG Episode Schematics & Teaching Click to enlarge! The CardioNerds 5! – 5 major takeaways from the #CNCR case 1. What is CAV?   CAV stands for cardiac allograft vasculopathy. Within the transplanted heart, CAV is the proliferation of vascular smooth muscle and intimal thickening in the epicardial coronary arteries and microvasculature leading to diffuse narrowing. CAV is common, present in greater than 30% of patients at 5 years post-transplant. It is a significant contributor to post-transplant mortality after the first year.   CAV, in contrast to typical atherosclerotic lesions, is diffuse and concentric while atherosclerosis tends to be focal with eccentric luminal narrowing and heterogenous plaque composition. Patients s/p OHT can still develop typical coronary artery disease, likely developed from pre-existing disease in the donor heart. CAV should be high on the differential for the cause of graft dysfunction, especially after the first year post-transplant.   2. How and Why Does CAV Occur?  CAV has multiple contributing factors. There are immunologic and non-immunologic factors, but it appears the immunologic components play the larger role given that the pan-vasculopathy develops in the donor heart and not in the recipient’s vasculature. In CAV, there is chronic immune-mediated injury creating a persistent inflammatory state in the donor coronary endothelium leading to a neointimal proliferative process in the coronaries. Amongst immunologic factors, it appears the number of episodes of cellular rejection correlates with the development of CAV.   CAV occurs when foreign anti

The patient presented with a STEMI following a diagnosis of EVALI. What is known about the cardiovascular risks of vaping and e-cigarette use?  The overall cardiovascular risks of e-cigarette use remains to be elucidated  In preclinical studies, e-cigarettes use have been linked to increased sympathetic activity, oxidative stress, endothelial dysfunction, vascular injury, and altered platelet activity  One observational study has suggested that daily e-cigarette users were 1.79 times more likely to experience MI than individuals who had never used e-cigarettes.  Additional high-quality randomized controlled trials are needed to conclusively establish the safety and efficacy of e-cigarettes.  2. So the data is still emerging regarding the overall cardiovascular risks of e-cigarette use. Of note, the patient had a negative stress test a month prior. Should that not translate into low likelihood of cardiovascular events?  Remember that stress testing for the diagnosis of obstructive coronary disease is most helpful in patients with an intermediate pretest probability for coronary artery disease. Further myocardial ischemia can occur not only secondary to obstructive epicardial disease (which may be new and acute from plaque rupture/erosion), but also from microvascular disease, vasospastic disease, and so forth.

EKG showed anteroseptal and lateral STE with reciprocal ST depressions in the inferior leads. High-sensitivity troponin was elevated at 333 ng/mL. Emergent LHC showed a long and narrow left main with areas of additional contrast filling into a false lumen with no flow in the LAD. RCA and LCx were normal appearing (make sure you check out the angiogram videos below!). IVUS showed dissection and heavy thrombus burden in the left main artery. Shortly after the diagnostic angiogram, the patient went into V-fib arrest and received one shock with ROSC. Amiodarone was started and an Impella CP was placed for additional left ventricular support. ECMO and emergent CABG were not readily available at this time so the interventional team attempted revascularization with PCI to the left main given patient’s hemodynamic instability from ongoing ischemia. However, even after PCI to left main, flow to LAD remained poor and the LCx now also appeared occluded. The decision was made to cease further attempts at revascularization. Unfortunately, post-procedure TTE showed a reduced EF of 22% with anterior and anterolateral hypokinesis. She was transferred to CCU on maximal Impella support. Patient eventually developed acute renal and liver failure secondary to cardiogenic shock and suffered an additional V-fib arrest with ROSC. Eventually, Ronald Reagan UCLA was contacted for transfer and the mobile ECMO team was dispatched. They placed the patient on VA-ECMO in the outside facility and transferred her to Ronald Reagan UCLA. At Ronald Reagan, revascularization was attempted given persistent cardiogenic shock and 3 stents were successfully deployed in the LAD. She was eventually weaned off of both Impella and ECMO after successful PCIs to LAD. However, TTE showed persistently low EF and patient eventually underwent successful heart-kidney transplantation.  Case Media A B C D Click to Enlarge A.

A nuclear stress test showed a reversible perfusion defect in the RCA territory, and he was referred for PCI. Coronary angiogram showed severe stenosis of the proximal RCA and a DES was successfully deployed with TIMI 3 flow, though several large acute marginal branches were jailed.   The night following PCI, the patient developed bradycardia, hypotension, and tachypnea. Physical exam showed newly elevated JVP, lower extremity edema, and bibasilar crackles without a new cardiac murmur. ECG showed ST elevation in V1-V4, and bedside echocardiogram showed a severely dilated RV with decreased systolic function. With concern for acute RV failure, the patient was fluid resuscitated, started on dopamine for chronotropy, and was admitted to the CCU. A Swan-Ganz catheter was placed, showing a CVP 12, RV 41/15, PA 36/20 (25), PCWP 18, CI 1.6 (by Fick method). The calculated PAPi was 0.84.   The patient was transitioned to dobutamine to improve RV inotropy, epinephrine in the setting of hypotension, and inhaled nitric oxide in an attempt to decrease RV afterload. Despite these interventions, the patient had worsening shock, anuric renal failure requiring CVVH, and respiratory failure requiring intubation. A centrifugal RA to PA pump was placed (Protek Duo) for right-sided mechanical circulatory support, with improvement in RV hemodynamics and cardiogenic shock. Notably, a repeat angiogram was done, which showed a patent left coronary circulation as well as a right coronary artery without flow in the acute marginal branches. After 6 days of mechanical circulatory support, the patient was ultimately able to be weaned from vasoactive agents, and the Protek Duo was removed. He continued to have junctional bradycardia, and a permanent pacemaker was placed. After a nearly month-long admission, the patient was discharged to rehab; at 4 months follow-up, the patient’s RV function had improved on TTE, and he was not limited from heart failure symptoms.   Case Media A B C D E F G Click to Enlarge A: ECG, initialB: ECG: 8 hours post PCI he was noted to have junctional bradycardia with ST-segment elevations in V1-V4.C: Pre and post RCA PCI D: TTE: EF 50-55%, Severely enlarged RV with severely reduced systolic function, TAPSE 1.4 cm, Myocardial systolic excursion velocity (S’): 5.9E: CXR- shock F: Swan, Protek Duo Cannula, Temporary pacer G: CXR and TTE images demonstrating Protek Duo cannula placement Left Coronary System -1 Left Coronary System – 2 Severe eccentric serial stenoses in the proximal to mid RCA – 1 RCA – 2 RCA PCI – 1 RCA PCI – 2 RCA PCI – 3 RCA PCI – 4 RCA – Final TTE -1 TTE -2 Repeat angiogram: Patent stents, sluggish flow Prote

Her only medications were baby aspirin, atorvastatin 80mg, and thyroid replacement. Her blood pressures were noted to be dropping and so her regimen was being titrated off as a result. Physical exam was notable only for poorly palpable pulses in all extremities. To further work this up, a myocardial perfusion scan, CTA head/neck/abdomen, and ABIs were ordered. ABI on the right was 0.86 and on the left was 0.76 with monophasic doppler waveforms throughout. CT abdomen exhibited an occlusion of the abdominal aorta from just below the renal arteries extending to the common iliac arteries with distal reconstitution. CT head/neck showed occlusion of the right carotid artery, complete occlusion of the right innominate artery, near complete occlusion of the right vertebral artery, and delayed flow in the right posterior cerebral artery. On the left side, she had high-grade subclavian stenosis. Myocardial perfusion imaging exhibited no defects.   On subsequent visits her exercise tolerance improved with an exercise regimen, but blood pressures were more and more difficult to obtain. As a result, revascularization was pursued with stenting of the left subclavian artery. She was discharged, but returned a few hours later with severe left sided pulsatile headache and nausea/vomiting. She was admitted for monitoring, but fortunately improved and discharged with close outpatient follow-up.  She continued to improve in the outpatient setting. After MRI brain and extensive work-up, she was deemed to have cerebral hyperperfusion syndrome following revascularization.  She had no further complications and was monitored thereafter.  Final diagnosis: severe peripheral artery disease (PAD) and cerebral hyperperfusion syndrome.

A left groin AV loop graft was pursued due to multiple access point failures in the past secondary to severe peripheral artery disease. Pre-op evaluation included risk stratification with RHC which was consistent with WHO Group 2 pulmonary HTN and diffuse atherosclerosis in the RCA on LHC. Intra-op, patient had an episode of significant hypotension after administration of protamine that required phenylephrine and ephedrine. In the PACU, his BPs continued to be low (70s/40s mmHg), requiring admission to the SICU where cardiology was consulted.  In the SICU, patient had ongoing hypotension despite pressors and fluids. Exam demonstrated a systolic murmur consistent with TR and elevated JVP. Labs were notable for a mild elevation in liver enzymes, elevated troponin, high NT-proBNP and elevated lactate. TTE demonstrated a moderately dilated and hypokinetic RV, elevated RVSP and evidence of pressure/volume overload. CTA abdomen/pelvis demonstrated extensive mesenteric atherosclerosis and signs of gastric ischemia. Patient was treated for RV failure with norepinephrine, inhaled epoprostenol, and CVVHD for volume removal. He became febrile and was treated empirically with broad spectrum antibiotics. Due to concern for the new loop graft causing high output heart failure vs RV failure, it was temporarily occluded for testing and then permanently ligated by vascular surgery with significant improvement in his BPs and RV function on repeat TTE.  Case Media A B C D E Click to Enlarge A.

She received 6 rounds of CPR and 2 shocks before ROSC was achieved. She was intubated and given fluids but continued to remain hypoxic and hypotensive. Exam demonstrated sinus tachycardia, no murmurs, gravid abdomen and cool extremities. Initial labs demonstrated leukocytosis to 14k, lactic acid at 4.3 mmol/L, troponin-I peak at 0.07 ng/dL and elevated NT-proBNP. CXR demonstrated bilateral effusions and pulmonary congestion, and post-arrest EKG showed a wide complex tachycardia, leading to suspicion of VT arrest. In sinus, there  were no ST segment elevations and TTE showed LVEF 10-20%, global hypokinesis and no valvular disease. Given the severity of her shock, she was placed on central VA-ECMO with Impella support as an LV vent. During ECMO cannulation, she underwent emergent cesarean section due to fetal distress. Coronary angiography showed non-obstructive coronaries, but with sluggish flow in the setting of her cardiogenic shock and possible coronary spasm in setting of multiple vasoactive medications. Endomyocardial biopsy was negative for giant cell myocarditis. Within 4-5 days, she was weaned off all vasoactive agents and ECMO was decannulated; repeat echocardiogram showed LV functional recovery. GDMT was slowly titrated and a subcutaneous ICD was eventually placed before discharge.

The CardioNerds 5! – 5 major takeaways from the #CNCR case 1. What is the differential for cardiac arrest in pregnant patients?  When thinking about a cardiac etiology of arrest, the differential should include pregnancy-induced hypertension, peripartum cardiomyopathy, myocardial infarction from acute coronary syndrome or spontaneous coronary artery dissection, pulmonary embolism, amniotic fluid embolism and aortic dissection. Non-cardiac etiologies include hemorrhagic shock, sepsis, stroke, trauma and anesthetic complications. In addition to these unique considerations, pregnant patients are also susceptible to the usual culprits!  As noted in the 2015 AHA Scientific Statement, cardiac arrest in pregnancy is not common, occurring in 1:12,000 admissions for delivery. As of 2016, per the CDC the pregnancy-related mortality rate was ~17 deaths per every 100,000 live births. However, mortality data does not fully capture critical illness in pregnancy, and thus the AHA recommends considering maternal “near-miss” data.   Knowledge gaps, provider unfamiliarity, and lack of medical ward or medi

Prior to his arrest, his coworkers reported that he was complaining of lightheadedness, dizziness and that he was found slumped over at his desk. His EKG in the ambulance showed STE in aVR and V1 – V4 with TWI in III and aVF initially concerning for an anterior STEMI. He was cannulated with VA-ECMO for extracorporeal cardiopulmonary resuscitation (E-CPR) and was taken to the catheterization lab emergently. In the catheterization lab, his coronary angiogram did not show obstructive coronary disease. The interventionalists decided to perform a pulmonary artery (PA) angiogram which revealed a large amount of thrombus bilaterally in the proximal PAs. He underwent surgical embolectomy with removal of almost all his clot burden. The patient was thereafter cooled for neurological protection. Unfortunately, the patient had a very poor neurological exam with lack of brainstem reflexes upon rewarming. There was loss of gray-white differentiation on CT, and EEG and evoked potential testing were consistent with severe anoxic brain injury. After discussions with the patient’s family, the patient was transitioned to comfort care and subsequently passed away peacefully.   Case Media Click to Enlarge Right Coronary Artery Left Coronary System – 1 Left Coronary System – 2 Left Pulmonary Artery Right Pulmonary Artery Episode Schematics & Teaching Click to enlarge! The CardioNerds 5! – 5 major takeaways from the #CNCR case The patient presented initially with STE in aVR as well as the septal and anterior leads. What is the differential for an ST elevation in lead aVR? STE in aVR with diffuse ST depression can be a potential finding of LM or LAD stenosis. However, there have been several studies that have shown that the combination of STE and multi-lead STD was not associated with complete occlusion of a culprit vessel. Thus, the differential for STE in aVR more commonly includes significant LM or LAD stenosis, severe three-vessel disease with diffuse sub-endocardial ischemia (e.g., CAD in the setting of sepsis, anemia, shock), as well as pulmonary embolism with right ventricular injury (see below)! Remember that lead aVR is opposite I, aVL, II and V5-6 and thus elevation in aVR may represent reciprocal changes of diffuse sub-endocardial ischemia. Furthermore, aVR doesn’t directly overlie myocardium but reflects electrical activity from the RV outflow tract and basal septum. Thus, in the context of an anterior STEMI, STE in aVR (> 1mm) strongly predicts LAD occlusion proximal to the first septal perforator, which supplies the basal septum. The patient was found to have non-obstructed coronaries and was ultimately diagnosed with a PE. Could we have suspected that from the initial EKG? What are the EKG changes that have been noted i

She reported intermittent pleuritic chest discomfort that had persisted since an episode of acute pericarditis years prior. A TTE suggested severe mitral regurgitation, and she was referred to the Mayo Clinic for mitral valve intervention.    The official TTE report from the OSH suggested non-dilated LV, EF 55-60%, normal RV function, severe MR with thickened leaflets and sub-valvular apparatus, moderate to severe TR and a dilated IVC. Furthermore, the CXR showed pericardial calcifications. Upon evaluation by the Mayo Clinic fellows, the JVP was elevated to about 10-12 cm with rapid x and y descents, a positive Kussmaul’s sign, and the murmurs of MR and TR. Her lungs were clear to auscultation and extremities did not demonstrate edema. Re-review of the TTE images revealed posterior pericardial thickening, no septal shift on respiration, but suggestion of annulus reversus where medial mitral annulus tissue doppler (9 cm/s) was greater than lateral (8 cm/s). Further, there was evidence of expiratory hepatic vein diastolic flow reversal.  For the team, there was discordance between the apparent severity of her MR reported by echocardiogram and her clinical symptoms. In addition, the echocardiogram was suggestive of specific signs of constrictive pericarditis. Thus, simultaneous RHC/LHC was obtained. There was equalization of RV/LV pressures during diastole, demonstration of a “square root sign” and importantly discordance between LV and RV pressures with respiration. Thus, discordant clinical findings led to a suspicion for constrictive pericarditis and was corroborated by discordance on invasive hemodynamics! Further, the V-waves were not prominent on wedge pressure tracing and to investigate the mitral regurgitation further, an LV ventriculogram was done. This demonstrated 3+ to 4+ MR.  Based on all the findings, the patient was diagnosed with constrictive pericarditis, severe MR and moderate to severe TR. She underwent pericardiectomy, mitral valve replacement (given that repair was not feasible due to the sub-valvular thickening) and given that TR has been shown to worsen after pericardiectomy and is a poor prognostic factor, she additionally underwent tricuspid valve repair. Her symptoms improved markedly following intervention.  Case Media A B C D E F G H Click to Enlarge A.

He appeared grossly volume overloaded on exam with JVP elevated past the mandible, RV heave, and 2+ pitting edema. TTE demonstrated LVEF of 55-60%, RVSP 40mmHg, abnormal septal motion with respiration, and respirophasic variation in mitral inflow across the mitral valve raising the suspicion for constrictive pericarditis. RHC pressures demonstrated a mean RA pressure of 20mmHg, RV 40/25mmHg, PA 38/30mmHg (mean 32 mmHg) and PCWP mean of 26 with V-waves at 28 mmHg. Simultaneous LV and RV pressure tracings showed ventricular discordance with respirophasic variation, consistent with constrictive physiology. Patient underwent pericardiectomy with markedly improved heart failure symptoms. Repeat TTE showed no evidence of constriction.  Case Media A B C Click to Enlarge! A. ECGB.

Episode Schematics & Teaching Click to enlarge! The CardioNerds 5! – 5 major takeaways from the #CNCR case The initial presentation clinically seemed to be right greater than left heart failure. What are the signs and common causes of right heart failure?    The signs and symptoms of RHF are often similar to left-sided CHF, but may describe more severe dyspnea on exertion, significant abdominal distension, and early satiety due to ascites or gut edema. Symptoms of pulmonary edema from elevated left-sided filling pressures (orthopnea, paroxysmal nocturnal dyspnea) may be absent. On examination, there will be elevated JVP with likely prominent v-waves, possibly Kussmaul’s sign (inspiratory rise in JVP rather than fall) depending on the pathology, abdominal ascites, pulsatile hepatomegaly, and lower extremity edema. An RV heave may be discernible along with a loud P2 component and murmur of TR. Broadly, RV failure may be caused by pressure overload (ex: pulmonary hypertension, pulmonic stenosis), volume overload (ex: intracardiac shunt, tricuspid regurgitation), or myocardial disease (ex: cardiomyopathies, ischemia/infarct). The most common cause of chronic right heart failure is LV failure (causing post-capillary pulmonary hypertension). Other causes of RV failure include pre-capilla

Limited TTE found LVEF <20% and a LV apical thrombus; she was started on milrinone due to concern for cardiogenic shock and transferred to the University of Pennsylvania.  Upon arrival, she was found to be hypotensive and tachycardic. Exam was notable for elevated JVP, +S3, LE edema and R sided hemiparesis. Labs showed multiorgan injury, elevated NT-proBNP and elevated lactate. EKG demonstrated sinus tachycardia with no ST-T changes. Formal TTE showed severely dilated LV with EF 10%, diffuse LV hypokinesis, and confirmed a large LV apical thrombus. A pulmonary artery catheter was placed for tailored therapy and found elevated L-sided > R-side filling pressures with low cardiac index despite inotropes. Cardiac power output (CPO) was severely decreased with borderline pulmonary artery pulsatility index (PAPI), corroborating left > right heart failure. Patient ultimately required a durable left ventricular assist device (LVAD). Over the course of 9 months her guideline directed medical therapy (GDMT) was titrated and her intrinsic cardiac function and symptoms improved. Her EF improved to 35-40% and she tolerated an LVAD weaning protocol, so her LVAD was ultimately explanted! She is currently doing well on GDMT alone!   Case Media CXR: Mild interstitial edema, +ET tube ST (131), LAD, nonspec T wave flattening, nl intervals Click to Enlarge TTE 1 TTE 2 Episode Schematics & Teaching Click to enlarge! The CardioNerds 5! – 5 major takeaways from the #CNCR case 1. How do we define Peripartum Cardiomyopathy?   Diagnosis is made by the development of heart failure towards the end of pregnancy or in the months following delivery (~5 months postpartum), no other identifiable cause of HF, and demonstration of LV systolic dysfunction with LVEF typically less than 45% with or without dilation.  Risk factors include history of pre-eclampsia, hypertension, cocaine use, multifetal pregnancies, older maternal age, and African descent.     Keep a broad differential diagnosis for new onset heart failure in the peripartum period. The differential includes pre-existing cardiomyopathy, valvular disease or congenital cardiomyopathy unmasked by the hemodynamic changes of pregnancy (see CNCR episode 48 for more on the hemodynamic changes of pregnancy!). Other differentials should include ischemia/spontaneous coronary artery dissection (SCAD), stress-induced cardiomyopathy, CM due to systemic disease (e.g. sepsis, rheumatologic disease), myocarditis and tac

They recurred two years prior, when he was diagnosed with paroxysmal atrial fibrillation. Finally, he was hospitalized one month before presentation with multiple ICD shocks and was found to have high defibrillation thresholds (DFTs) and amiodarone was stopped. He  then presented for a second opinion from the Northwestern CardioNerds!  The patient had been doing well on GDMT and had NYHA Class I symptoms (Enjoy Ep #13 – Approach to GDMT). He did note a family history of a cousin with “cardiac issues” and did not know his father’s family history. Physical exam demonstrated bradycardia and ECG demonstrated an a-paced, v-sensed rhythm at 50 bpm. TTE demonstrated a moderately dilated LV with LVEF 30%, globally reduced LV function and multiple wall motion abnormalities without a vascular distribution.  PET-CT was performed which showed diffuse uptake and high-intensity signal at the inferolateral and basal anterior walls. Cardiac MRI showed diffuse circumferential epicardial delayed enhancement with associated diffuse, enhancing thickening of the pericardium favoring inflammatory versus fibrotic process. Patient was initially diagnosed with cardiac sarcoid and started on prednisone and weekly methotrexate.   On return of genetic testing, patient found to have a pathogenic variant for desmoplakin gene, and it was felt his cardiomyopathy was secondary to desmoplakin Left Dominant Arrhythmogenic Cardiomyopathy (LDAC, or left-dominant ARVC) presenting with inflammatory myocardial injury. On follow up the patient remained listed for transplant, and DFTs improved off amiodarone.   Case Media CXR ECG Cardiac MRI PET CT (Cardiac Sarcoid Protocol) Click to Enlarge Episode Schematics & Teaching Created by Dr. Karan Desai Click to enlarge! The CardioNerds 5! – 5 major takeaways from the #CNCR case We started the case talking about DFTs. What are DFTs?!  Defibrillation Thresholds (DFTs) are the minimal amount of energy required to return a patient to sinus rhythm that is in a cardiac dysrhythmia.   Most modern ICD leads have thresholds less than 15 joules and typically less than 10 joules with biphasic shocks. High DFT thresholds tend to be defined as >25J or a safety margin of <10J.  DFT testing is not routinely recommended during implantation of left-sided transvenous devices; however, in patients undergoing right-sided transvenous ICD or ICD pulse generator changes, DFT testing is a reasonable approach.

She underwent successful implantation of a 29mm Medtronic Evolut Pro valve via left common femoral artery access. Post-valve deployment and following protamine administration for heparin reversal, course was complicated by hypotension with PEA arrest requiring CPR for 4 minutes. Intra-op TEE and angiogram showed a well-seated prosthetic valve with trace paravalvular leak and no evidence of acute aortic regurgitation, significant paravalvular leak, pericardial effusion, coronary obstruction, aortic dissection, or access site complications. She was treated for suspected Protamine reaction with high dose steroids & epinephrine. However, she remained hypotensive with MAP in the 50s on high dose Epinephrine, Norepinephrine, and Vasopressin. Hemodynamics by pulmonary artery catheter demonstrated CVP 7, mPA 26, PCWP 18 mmHg and CO/CI 2.8 L/min and 1.3 L/min/m2. Her lactate was elevated at 5.92 mmol/L and EKG demonstrated normal sinus rhythm. Bedside TTE in the ICU showed hyperdynamic LV function with LVEF 70% and near-complete mid to distal cavity obliteration with significant intracavitary gradient. She was diagnosed with post-TAVR suicide LV and managed with aggressive volume resuscitation and rapid wean of Epinephrine/Norepinephrine with improvement in her hemodynamics.

But remember, in HF patients decreased trans-aortic valve flow secondary to LV disease can make the diagnosis challenging!  In HFrEF, patients with severe AS by aortic valve area (AVA) may not meet velocity or gradient criteria in one of four contexts: AVA measurement error, pseudo-severe AS, poor contractile reserve, or true severe Low Flow, Low Gradient AS (LFLG AS).  Similarl

The CardioNerds 5! – 5 major takeaways from the #CNCR case Cardiac amyloidosis can have a range of cardiac and extra-cardiac findings as amyloid fibrils can deposit in many different tissues, depending on the amyloid protein involved. The first step in diagnosis is maintaining a high index of suspicion. The presence of prominent right-sided HF symptoms, low voltage on ECG, biatrial enlargement, ventricular hypertrophy, conduction disease, and pericardial effusion should prompt a high suspicion for cardiac amyloid. These are typical features of infiltrative or storage restrictive cardiomyopathies. PEARL: ATTR CM can cause asymmetric LVH and is an important HCM phenocopy! Remember, amyloidosis is a systemic disease and extra-cardiac findings are common. ATTR amyloid has a predilection for the musculoskeletal system (including bilateral carpal tunnel syndrome, lumbar spinal stenosis, and biceps tendon rupture) and peripheral nerves. Conversely, AL amyloid is widely deposited outside the CNS an can result in protean manifestations, including periorbital ecchymoses from vascular fragility, macroglossia, and visceral org

Family history was negative for DVT/PE or hypercoagulable states. On exam, she was euvolemic. Labs were significant for anemia, a normal pro-BNP, and a negative extensive hypercoagulable workup. TTE showed interventricular systolic septal flattening, right ventricular outflow tract pulse wave doppler with mid-systolic notch, and shortened acceleration time consistent with elevated pulmonary artery pressure. A VQ scan showed bilateral right greater than left mis-matched perfusion defects. CT angiogram showed right greater than left chronic mural thrombus, correlating with pulmonary angiogram which showed severe proximal and mid-vessel disease on the right and distal disease on the left. RHC corroborated the diagnosis of chronic thromboembolic pulmonary hypertension (CTEPH) with mean pulmonary artery pressure of 41 and PVR of 5.2 Woods Units (WU).   To determine the etiology of her recurrent clots, a lower extremity venogram was performed and showed 80% stenosis of her left common iliac vein by the overlying right common iliac artery confirming May-Thurner syndrome. Lower extremity venogram also showed severe proximal stenosis of right iliac vein thought to be due to large uterine fibroids. Given her severe proximal and mid-vessel clot burden, she underwent pulmonary thromboendarterectomy with a subsequent drop in pulmonary vascular resistance to 1 WU.  The etiology of DVTs and CTEPH was determined to be external compression related to both May-Thurner syndrome and uterine fibroids. To prevent future thromboembolic events, she underwent stenting of her left common iliac vein and hysterectomy.

She was found to have an elevated troponin, anterior T wave inversions, and apical akinesis on TTE. Coronary angiography showed a coronary embolism in the mid-distal LAD. Attempts to wire the lesion led to distal embolization of the clot, and IVUS showed no underlying arteriosclerosis.   To investigate the etiology of the coronary embolus, a repeat TTE with agitated saline was done that suggested a PFO with right to left flow, as well as decreased RV function with an estimated RVSP of 70 mmHg. The clinical picture was that of a paradoxical coronary embolus, arising from the right (venous) side traveling to the left (arterial) side via a PFO. PFO closure was discussed but not performed given severe pulmonary hypertension with Right to Left shunt. In this circumstance, the PFO functions as a “pop-off valve” for the overloaded RV; closing it risks precipitating acute RV overload and failure. A RHC showed a PA pressure of 70/24 mmHg with mPAP of 40 mmHg, PCWP 5 mmHg, and PVR of 11 woods units. Given concern for idiopathic PH, a vasodilator challenge was done which did not show reactivity, and she was started on ambrisentan and sildenafil. Ultimately, the etiology of her pulmonary hypertension was felt to be due to PAH from prior methamphetamine use vs. idiopathic PAH. On follow-up, her PA pressures and RV function had greatly approved, allowing for safe and successful PFO closure in an attempt to prevent future emboli.  Final diagnosis: Embolic Acute Coronary Syndrome from PFO & Pulmonary Hypertension.

We can think of the etiology of coronary emboli in three major categories: Direct, Paradoxical, or Iatrogenic.  Direct emboli originate from the left side of the heart: sources include clot (from atrial appendage, apical thrombus), valvular lesion (vegetation, thrombus, fibroelastoma), or left sided cardiac mass (atrial myxoma, rhabdomyosarcoma).  Paradoxical emboli originate from the right side or systemic venous circulation, and pass from right to left through an atrial septal defect, patent foramen ovale, or pulmonary arteriovenous malformation.  Iatrogenic emboli occur following procedures such as valve replacement or PCI. Note that iatrogenic is the most comm

He was found to be grossly volume overloaded, tachycardic in atrial fibrillation, and hypoxic. CXR demonstrated significant cardiomegaly, and labs indicated new normocytic anemia with evidence of hepatic dysfunction and an elevated NT proBNP. TTE demonstrated massive bi-atrial enlargement, preserved ejection fraction, filling pattern consistent with grade III diastolic dysfunction, and torrential TR. The echocardiogram did not have evidence of constrictive pericarditis and agitated saline study showed Right to Left shunt through a likely PFO. MRI to evaluate for infiltrative cardiomyopathy did not show late gadolinium enhancement (LGE). RHC demonstrated findings consistent with restrictive cardiomyopathy including equalization of diastolic pressures, square root sign, and concordance of RV and LV pressures. PYP scan evaluating for TTR amyloid was negative and laboratory workup did not suggest AL amyloid, Fabry’s, Hemochromatosis, or storage disease. Patient’s symptoms remained refractory and thus eventually underwent successful OHT. Genetic testing eventually revealed missense mutation in MYBPC3 – revealing an inherited cause of restrictive CM for the patient!  Case Media Chest X-ray -Rate-controlled A fib with frequent PVCs, LPFB, non-specific ST changes https://youtu.be/LTUaLd2R7js Episode Schematics & Teaching Click to enlarge ??? The CardioNerds 5! – 5 major takeaways from the #CNCR case When thinking about the etiology of a restrictive cardiomyopathy, we can organize the causes into four major categories: Infiltrative (e.g., amyloidosis, sarcoidosis) Storage diseases (e.g., hemochromatosis, Fabry’s) Non-infiltrative (e.g., idiopathic, diabetic cardiomyopathy, genetic causes) Endomyocardial (e.g., endomyocardial fibrosis, hypereosinophilic syndrome) On examination, patients with restrictive cardiomyopathy may have prominent right-sided symptoms, including hepatomegaly, ascites, and significant peripheral edema. On exam, neck veins may demonstrate a steep y descent, and cardiac auscultation may have a +S4, and murmurs of tricuspid and mitral regurgitation. A multimodal imaging workup is recommended for evaluating RCM. TTE: Typically demonstrates normal LVEF, normal chamber volumes, biatrial enlargement, and restrictive diastolic filling patterns (.e.g, E/A > 2, E/e’ > 14, decreased mitral deceleration time < 150 ms). We can see increased wall thickness with infiltrative processes and storage diseases. cMRI: specific patterns of Late Gadolinium Enhancement may indicate certain pathology (e.g., amyloid may demonstrate diffuse subendocardial, heterogeneous, or transmural signal). T2 signal can identify inflammation and quantify iron. PYP scan: It has a >99% sensitivity for cardiac A

There was no loss consciousness, pre-syncopal symptoms, chest pain, aura, weakness, or palpitations. She had no recent preceding illness. When she arrived in the ED she was hypoxic to 87% on ambulation on room air and required 4L of nasal cannula O2 supplementation. The AGH CardioNerds were consulted!   On examination, the team noted that upon sitting up the patient would desaturate to the mid 80% but when lying down oxygen saturation would improve to 95%! Her ECG demonstrated a RBBB and no acute ST-T changes. TTE was obtained and showed normal LV and RV function and size, no valvular disease, and a likely PFO on an agitated saline study. Cardiac MRI revealed mild RV hypertrophy and Qp:Qs of 0.8 (right/pulm cardiac output < left/systemic cardiac output, indicating right to left shunting).  RHC showed normal right-sided pressures. A right femoral vein bubble study  was done showing torrential right to left shunting! She underwent PFO closure and her platypnea-orthodexia resolved; she was discharged on room air.  Case Media Episode Schematics & Teaching The CardioNerds 5! – 5 major takeaways from the #CNCR case Platypnea-orthodeoxia syndrome (POS) is when dyspnea (Platypnea) and hypoxia (Orthodeoxia) are present in the upright position, but improve upon lying flat. One cause is ARLIAS, or Acute Right-to-Left Inter-Atrial Shunting, which requires an anatomic component (I.e., ASD or PFO) and a functional component (I.e., PH, PE, RV failure) for Right-to-Left shunting to occur  A PFO, or patent foramen ovale is a common congenital defect and typically will not lead to hypoxia unless there is right to left shunting. Typically flow is left to right due to an LA to RA pressure gradient and lower compliance of the RV.   Remember when evaluating for a PFO with agitated saline, the timing of the appearance of bubbles is important!  Early appearance of bubbles (seen in less than 5 beats of the cardiac cycle, think about intra-cardiac shunt. Delayed opacification (> 5 to 6 beats) occurs when the bubbles slowly build in the LV with each successive beat as they circulate to the LV and suggests extra-cardiac shunt.   Cardiac MRI is helpful in quantifying the shunt fraction (Qp:Qs).  This is the ratio of pulmonary flow (Qp) to systemic flow (Qs), where hemodynamically significant Left-to-Right shunt is > 1.5, especially when we see RA/RV dilation. Qp/Qs < 1.1 indicates net R to L shunt. Other ways to measure a Qp:Qs are echocardiogram (less accurate) and right heart catheterization.   If there remains clinical concern for PFO with right to lef
