Use of bioresorbable vascular scaffolds in patients with stable angina and acute coronary syndromes. Polish National Registry

Abstract

Background: Current revascularisation guidelines recommend coronary stenting with either a bare metal stent or a drug eluting stent. The results of bioresorbable vascular scaffold (BVS) implantation in the setting of both stable angina and acute coronary syndrome (ACS) have proven to be both safe and efficacious. Aim: To describe current use and real life experience among Polish percutaneous coronary intervention (PCI) operators in using BVS since they were made commercially available on our market. Methods: We performed a one-arm retrospective observational registry study which enrolled patients in 30 invasive cardiology centres in Poland who had their PCI procedure performed between October 2012 and November 2013. All patients who received at least one BVS stent during index PCI were included in the registry. There were no additional inclusion or exclusion criteria. Results: There were 591 patients enrolled in the registry in 30 centres in Poland. Of these, 48% were with stable angina (CCS I-III) and 52% with ACS (23% unstable angina, 18% NSTEMI and 11% STEMI). Radial access for PCI was used in 70% of cases. Left anterior descending was the target lesion in 48% of patients and predilatation used in 90%. PCI complications occurred very rarely with dissection in 2.9% of patients, slow-flow in 0.5%, no-reflow in 0.17%, and side branch occlusion in 0.33%. Technical success, defined as successful BVS delivery to the lesion, was achieved in all cases (100%). There were no periprocedural deaths. Conclusions: The early in-hospital results of this large scale national registry of 'real world' utilisation of BVS in Poland present excellent device performance in a properly selected group of patients with appropriate lesion preparation.
