title: Late stent thrombosis of a second-generation drug- eluting stent.
abstract: A 62-year-old male patient presented with acute non-ST elevation myocardial infarction. He underwent successful percutaneous coronary intervention with implantation of an everolimus-eluting stent in the left anterior descending coronary artery. Six months later, he discontinued clopidogrel. Two weeks later, he presented with unstable angina. Despite the unremarkable electrocardiography, cardiac biomarkers, and coronary angiography, optical coherence tomography revealed a thrombus extending throughout the stent, with uncovered and malapposed stent struts in its proximal part. Thrombectomy was performed. The patient was discharged on dual antiplatelet therapy. Eight months later, the follow-up coronary angiography reassured a patent stent with adequate flow and no evidence of thrombi.
