Journal: Circulation PubMed Link: https://pubmed.ncbi.nlm.nih.gov/40927852 Summary: The LIFE-BTK trial demonstrated that, at two years, drug-eluting resorbable scaffolds showed no statistically significant difference in the primary patency rate compared to percutaneous transluminal angioplasty in patients with chronic limb-threatening ischemia undergoing infrapopliteal intervention. While scaffold thrombosis was higher in the drug-eluting resorbable scaffold group, major amputation rates were similar between the two groups. This suggests that while the resorbable scaffold does not improve patency, it also does not increase the risk of limb loss.
