Aim and Objective We sought to investigate and compare outcomes 2 years after Hybrid-stenting with bioresorbable vascular scaffolds (BVS) and contemporary metallic drug-eluting stents (DES) within the same coronary lesion versus BVS alone. Methods Between 11/2012 and 7/2015 at our institution, 134 (33.2%) were treated with Hybrid-stenting for complex or long coronary lesions, 270 patients were treated by BVS alone. The primary outcome of interest was target lesion failure (TLF) at 2-years of follow-up. Results Patients treated by Hybrid-stenting were more frequently men (80% vs. 70%, p = 0.04) had extensive multivessel disease (84% vs. 71%, p < 0.01) including more complex (89% vs. 52%, p < 0.01) and longer lesions (28.9 mm vs 16.4 +/- mm, p < 0.01) resulting in longer treated segments (47.3 mm vs 21.5 mm, p < 0.01) and more residual in-segment stenosis (12.3% vs 8.5%, p < 0.01) compared to BVS alone patients. At 2 years, cumulative incidence of TLF was 9.7% of Hybrid-stenting patients and 11.5% of BVS alone patients (p = 0.62), myocardial infarction (3.0% vs 4.1%, p = 0.59) and mortality (1.5% vs 4.1%, p = 0.17), respectively. Target lesion revascularization occurred in 9 Hybrid-stenting patients (2 located in DES) and in 20 BVS alone patients, cumulative incidence 6.7% vs. 7.4% (p = 0.80). Chronic kidney disease and residual in-segment stenosis >30% were identified as independent predictors of TLF at 2-years. Conclusion Despite differences in clinical and angiographic profile, Hybrid-stenting performed similar to BVS alone at 2 years after percutaneous coronary intervention.
