Very late scaffold thrombosis of everolimus-eluting bioresorbable scaffold following implantation in STEMI after discontinuation of dual antiplatelet therapy.

A 42-year-old male with a history of smoking and dyslipidemia was admitted due to ST-elevation myocardial infarction. Coronary angiography showed severe stenosis in proximal right coronary artery (RCA) and total occlusion in mid RCA. Absorb everolimus-eluting bioresorbable scaffolds were deployed in mid and proximal RCA. The patient was discharged with dual anti-platelet therapy. Patient was admitted 15-months later due to acute coronary syndrome with scaffold thrombosis. Both aspirin and clopidogrel had been discontinued 1 month prior to the second event because of general malaise. Therefore, either aspirin or clopidogrel should have been continued even after 1 year following stent implantation.
