Three-Year Clinical Outcomes With The Absorb Bioresorbable Vascular Scaffold In Real Life: Insights From The France Absorb Registry
CATHETERIZATION AND CARDIOVASCULAR INTERVENTIONS(2021)
Abstract
Objectives The aim of this study was to determine the 3-year outcomes of patients treated with Absorb bioresorbable vascular scaffold (BVS) implantation.Background Randomized trials and observational registries performed in patients undergoing percutaneous coronary intervention have demonstrated higher 1-year and midterm rates of device thrombosis and adverse events with BVS compared to contemporary drug eluting stent. Data on long-term follow-up of patients treated with BVS are scarce.Methods All patients treated with BVS were included in a large nationwide prospective multicenter registry (FRANCE ABSORB). The primary endpoint was a composite of cardiovascular death, myocardial infarction, and target lesion revascularization at 3 years. Secondary endpoints were 3-year scaffold thrombosis and target vessel revascularization (TVR).Results Between September 2014 and April 2016, 2070 patients were included (mean age 55 +/- 11 years; 80% men). The indication was acute coronary syndrome (ACS) in 49% of patients. At 3 years, the primary endpoint occurred in 184 patients (8.9%) and 3-year mortality in 43 patients (2.1%). Scaffold thrombosis and TVR rates through 3 years were, respectively, 3 and 7.6%. In a multivariable analysis, independent predictors of primary endpoint occurrence were diabetes, oral anticoagulation, active smoking, absence of initial angiographic success and the association of a total BVS length >= 30 mm with the use of 2.5 mm diameter BVS.Conclusions Although 3-year mortality was low in this ACS population, device-related events were significant beyond 1 year. Total BVS length and 2.5 mm BVS were associated with higher rates of MACE at long-term follow-up.
