A 45-year-old man presented with acute anterior ST-elevation myocardial infarction four years after the implantation of two 3.0 mm diameter first-generation sirolimus-eluting CYPHER® (Cordis, Johnson & Johnson, Warren, NJ, USA) stents in his left anterior descending coronary artery. Emergent angiography (Moving image 1) now revealed a thrombotic occlusion of the distal stented segment (Panel A, yellow arrow), with peri-stent contrast staining in the proximal stented segment (Panel A, red arrows). Following thrombus aspiration, optical coherence tomography (OCT) (Moving image 2) showed positive arterial remodelling throughout the previously stented segments causing vessel evaginations (Panel B [blue arrows], Panel C) and malapposed stent struts (Panel B, Panel C [white arrows]), with occasional uncovered stent struts (Panel C, green arrow) and residual thrombus (Panel B, *).
