Bioresorbable Vascular Scaffold Compared With Minimally Invasive Bypass Surgery for the Left Anterior Descending Coronary Artery Disease: 12-Month Follow up

Abstract

Evaluates long-term clinical outcomes of percutaneous coronary intervention (PCI) with bioresorbable vascular scaffold (BVS) versus minimally invasive direct coronary artery bypass (MIDCAB) surgery for the treatment of left anterior descending (LAD) lesions. In this single-center study were included 130 patients with stable angina and significant (≥ 70 %) LAD disease. Patients were randomly assigned in a 1:1 ratio to PCI with everolimus-eluting BVS (n=65) or MIDCAB (n=65). Theprimary end-point was major adverse cerebro-cardiovascular events (MACCE) and secondary was scaffold (graft) thrombosis at1year. The groups of patients were comparable for all baseline demographic, clinical and angiographic parameters. MACCE at12month occurred in 9.2 % of patients in the BVS group and in 4.6 % of patients in the MIDCAB group (p=0.3). There was no significant difference between the groups in rates of all cause death (1.5 % vs 1.5 %, p=1.0), myocardial infarction (3.1 % vs. 6.1 %, p=0.4), any revascularization (1.5 % vs. 6.1 %, p=0.1) and scaffold (graft) thrombosis (1.5 % vs. 1.5 %, p=1.00). At 12-month follow up, there was no significant difference in the rate of MACCE between PCI by BVS and MIDCAB in patients with isolated LAD lesions.
