Bioresorbable vascular scaffold (BVS, ABSORB BVS1.1, Abbott Vascular) has been approved (CE mark) and is used in daily clinical practice. While recent randomized controlled trials comparing BVS versus metallic drug-eluting stent showed higher risk of definite or probable device thrombosis after BVS implantation, the causes underlying thrombotic events occurring beyond one year after scaffold implantation remain unclear and require investigation in an independent manner.
