Cardiovascular interventionsAbstract: BACKGROUND: Randomized trials have demonstrated the superiority of ultrathin strut drug-eluting stents compared with alternative stent designs. Whether these differences persist over late-term follow-up is uncertain.CONCLUSIONS: In a large, randomized trial, TLF and the individual outcomes of cardiac death and target lesion revascularization at 5 years were similar among patients treated with BP SES versus DP EES. Both target vessel-related myocardial infarction and late/very late definite/probable stent thrombosis were significantly lower with BP SES.

Prespecified outcomes through 5 years were assessed.OBJECTIVES: This study sought to compare late-term (5-year) clinical outcomes among patients treated with ultrathin strut (60 microm) bioresorbable polymer sirolimus-eluting stents (BP SES) and thin strut (81 microm) durable polymer everolimus-eluting stents (DP EES).RESULTS: Among 1,334 patients randomized to treatment with BP SES (n = 884) or DP EES (n = 450), the 5-year rates of TLF were 12.3% for BP SES and 15.3% for DP EES (P = 0.108). Revascularization with BP SES was associated with a significantly lower target vessel-related myocardial infarction (6.6% vs 10.3%, P = 0.015) and late/very late definite/probable stent thrombosis (0.3% vs 1.6%, P = 0.021). Ischemia-driven target lesion revascularization was numerically but not significantly lower with BP SES (5.9% vs 7.7%, P = 0.202). Cardiac death rates were 2.6% versus 1.9% (P = 0.495) for BP SES and DP EES, respectively.All authors: Bennett J, BIOFLOW V Investigators, Cutlip DE, Doros G, Garcia-Garcia HM, Gharib EG, Kandzari DE, Koolen JJ, Roguin A, Waksman RFiscal year: FY2023Digital Object Identifier: Date added to catalog: 2022-10-20
