Anatomical features and management of bioresorbable vascular scaffolds failure: A case series from the GHOST registry.

The Absorb bioresorbable vascular scaffold (Absorb BVS, Abbott Vascular, Santa Clara, California) promises to address some of the residual shortcomings of existing metallic stents, such as late events induced by permanent caging of the coronary vessel. Scaffold restenosis (ScR) of BVS has been poorly described so far and treatment strategies for this event remain to be codified. We report on a case series of 14 lesions in 12 patients presenting with ScR and discuss their anatomical features and management strategies. © 2015 Wiley Periodicals, Inc.

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 real-world 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.
