One-year outcomes after Absorb bioresorbable vascular scaffold implantation in routine clinical practice

Aims: Our aim was to report one-year outcomes of Absorb bioresorbable scaffold implantation under realworld conditions in an all-comers population of patients with high proportions of complex lesions. Methods and results: Patients undergoing Absorb 1.1 implantation were included in a single-centre, prospective, all-comers registry. The primary outcome was target lesion failure (TLF), defined as the combination of cardiac death, target vessel myocardial infarction (MI), or clinically driven target lesion revascularisation (TLR). A total of 319 patients received 604 Absorb BVS in 406 lesions. Of note, 24.8% of patients had diabetes and 49.5% presented with an acute coronary syndrome. A total of 51% of lesions were type B2/C. The reference vessel diameter and lesion length were 2.9±0.5 and 21.2±16.8 mm, respectively. The one-year cumulative rate of TLF was 4.9%. Rates of cardiac death, target vessel MI and TLR were 0.9%, 1.3% and 4.2%, respectively. The cumulative one-year rate of definite/probable scaffold thrombosis was 1.3%, with all events occurring within 30 days. Conclusions: These data suggest that twelve-month clinical outcomes of Absorb use in "real-world" unselected patients with high proportions of complex lesions are reasonably good.
