Late and very late coronary stent thrombosis: Intravascular ultrasound findings and associations with antiplatelet therapy

Late and very-late stent occlusion remains a serious complication of coronary stenting. Despite their high anti-restenotic efficacy, drug-eluting stents (DES) have been associated to more late-thrombosis as compared to bare-metal stents (BMS). The aim of this study is to analyze the clinical presentation, angiographic, and intravascular ultrasound (IVUS) findings in patients with late or very late stent thrombosis and the relationship with the antiplatelet regimen.
