Initial experience and clinical evaluation of the Absorb bioresorbable vascular scaffold (BVS) in real-world practice: the AMC Single Centre Real World PCI Registry

AIMS To report procedural and midterm clinical outcomes after the use of the second-generation Absorb everolimus-eluting bioresorbable vascular scaffold (Absorb BVS) in a real-world percutaneous coronary intervention (PCI) registry. METHODS AND RESULTS All patients assigned to treatment with the Absorb BVS in the Academic Medical Center, Amsterdam, between August 2012 and August 2013 were included in a prospective registry. A total of 135 patients were included in the study, including 53 (39%) acute coronary syndrome (ACS) patients (13% ST-segment elevation myocardial infarction [STEMI]). In total 159 lesions were treated, including 102 (62%) with a type B2 or C classification. Pre- and post-procedural quantitative coronary angiography (QCA) analyses showed an acute gain of 1.37±0.53 mm. An angiographic success rate was achieved in 152 (96%) of the lesions. Six-month follow-up was available in 97% of the patients. Six-month cumulative target vessel failure (composite of all-cause mortality, any myocardial infarction [MI] and target vessel revascularisation [TVR]) rate was 8.5%, including a 3.0% MI, 3.0% definite scaffold thrombosis, 6.3% target lesion revascularisation, and an 8.5% TVR rate. CONCLUSIONS The use of the Absorb BVS in a cohort reflecting daily clinical practice is feasible and associated with good procedural safety and angiographic success rate. In addition, six-month follow-up is associated with acceptable clinical outcomes.
