Nevertheless, several trials tried to prove the safety and efficacy profile of scaffolds, but with conflicting results. Methods: A systematic review and meta-analysis was performed. The search was carried out in PubMed, Google Scholar, Biomed Central and Cochrane Library between January and March 2017. Inclusion criteria: randomized clinical trials (RCT) comparing the Absorb BVS versus durable polymer cobalt-chromium Everolimus Eluting Stent. The outcomes analysed were all-cause mortality, cardiac death, ischemia-driven target lesion revascularization, target vessel myocardial infarction (MI), target lesion failure (TLF)/device oriented composite endpoints (DOCE), and device thrombosis. Fixed-effect meta-analysis was performed. Data were expressed as odds ratio (OR). Results: Overall 5674 patients were included (mean age 62.2±1.31 in drug eluting stents (DES) group vs . 62±1,47 in BVS group; P=0.942). DOCE (OR 1.16, 95% CI: 0.90–1.48; P=0.259, I 2 =0%), cardiac death (OR 0.86, 95% CI: 0.52–1.40; P=0.537, I 2 =0%) and all-cause death (OR 0.78, 95% CI: 0.53–1.15; P=0.205, I 2 =15%) did not differ between BVS and DES. Conversely, ischemia-driven target lesion revascularization was more frequent in the BVS group (OR 1.32, 95% CI: 1.01–1.73; P=0.039, I 2 =0%), as well as device thrombosis (2.2% vs . 0.6%, OR 2.94 95% CI: 1.71–5.05, P=0.0001, I 2 =0%) and target-vessel MI (5.4% vs . 3%, OR 1.66, 95% CI: 1.25–2.21, P=0.001, I 2 =0%). Conclusions: The implantation of BVS is associated with an increased risk of device thrombosis, ischemiadriven target lesion revascularization and target vessel MI. If longer follow-up or different implantation technique may change these findings should be addressed in future trials. UR - https://jtd.amegroups.org/article/view/14312
