Comparison of Everolimus- and Biolimus-Eluting Coronary Stents With Everolimus-Eluting Bioresorbable Vascular Scaffolds

Abstract Background The first CE-approved bioresorbable vascular scaffold (BVS) is effective at treating simple lesions and stable coronary artery disease, but it has yet to be assessed versus the best-in-class drug-eluting stents (DES). Objectives This study sought to compare the performance of a BVS with that of everolimus-eluting stents (EES) and biolimus-eluting stents (BES) in all-comer patients. Methods The EVERBIO II (Comparison of Everolimus- and Biolimus-Eluting Stents With Everolimus-Eluting Bioresorbable Vascular Scaffold Stents II) trial was a single-center, assessor-blinded study of 240 patients randomly assigned in a 1:1:1 ratio to EES, BES, or BVS. The only exclusion criterion was a reference vessel diameter >4.0 mm, which precluded treatment with BVS. The primary endpoint was angiographic late lumen loss (LLL) at 9 months. Secondary endpoints included patient-oriented major acute coronary events (MACE) (death, myocardial infarction [MI], and any revascularization), device-oriented MACE (cardiac death, MI, and target lesion revascularization), and stent thrombosis at the 9-month clinical follow-up. Results Follow-up angiography was performed in 216 patients (90.7%) at 9 months. In-stent LLL was similar between patients treated with BVS (0.28 ± 0.39 mm) and those treated with EES/BES (0.25 ± 0.36 mm; p = 0.30). Clinical outcomes were similar at 9 months: the patient-oriented MACE rate was 27% in BVS and 26% in the EES/BES group (p = 0.83) and the device-oriented MACE rate was 12% in BVS and 9% in the EES/BES group (p = 0.6). Conclusions New-generation metallic DES (EES/BES) were not superior to BVS in terms of angiographic LLL and clinical outcomes.
