Drug-eluting bioresorbable vascular scaffold (BVS) is a revolutionary treatment option for obstructive coronary artery disease in percutaneous coronary intervention. It restores blood flow to the myocardium but unlike permanent metallic stent, BVS dissolves in the body within 2 years. This allows the coronary vessel to regain its normal function and motion. The clinical efficacy and safety of BVS in the first-in-human trials have been reported with low major adverse cardiac event rates observed at short- and long-term follow-up. The incidence of BVS scaffold thrombosis (ST) in these studies was 0 %. There is limited data on the incidence of BVS ST in the real world. We report 2 cases of subacute ST involving BVS in our real-world practice and discuss on the possible mechanisms of these thrombotic episodes (with insights from intracoronary imaging studies).
