ObjectivesTo compare clinical outcomes of patients treated with overlapping versus non-overlapping Absorb BVS. Background: Limited data are available on the clinical impact of stent overlap with the Absorb BVS bioresorbable stent. Methods: We compared outcomes of patients receiving overlapping or non-overlapping Absorb BVS in the multicenter prospective RAI Registry. Results: Out of 1,505 consecutive patients treated with Absorb BVS, 1,384 were eligible for this analysis. Of these, 377 (27%) were in the overlap group, and 1,007 (73%) in the non-overlap group. The most frequent overlap configuration was the marker-to-marker type (48%), followed by marker-over-marker (46%) and marker-inside-marker (6%) types. Patients of the overlap group had higher prevalence of multivessel disease and higher SYNTAX score, and required more frequently the use of intravascular imaging. At a median follow-up of 368 days, no difference was observed between overlap and non-overlap groups in terms of a device-related composite endpoint (cardiac death, TV-MI, ID-TLR) (5.8% vs. 4.1%, P=0.20) or of a patient-related composite endpoint (any death, any MI, any revascularization) (15.4% vs. 12.5%, P=0.18). Cardiac death (1.0% vs. 1.3%, P=0.54), MI (4.5% vs. 3.6%, P=0.51), TVR (4.5% vs. 3.6%, P=0.51) and stent thrombosis (1.1 vs. 1.5%, P=1.00) were also comparable between groups. When assessing outcomes of the overlap population according to overlap configurations used, no difference was observed in terms of the device- or patient-related composite endpoints. Conclusions: Outcomes of patients with or without overlapping BVS were comparable at mid-term follow-up despite higher angiographic complexity of the overlap subset. (c) 2017 Wiley Periodicals, Inc.
