title: Late Strut Fracture Within a Partially Resorbed Bioresorbable Vascular Scaffold: A Possible Cause of Late Scaffold Thrombosis and Acute Coronary Syndrome.
abstract: The Bioresorbable Vascular Scaffold (BVS, Abbott Vascular, Santa Clara, Cal, USA) is an exciting advance in percutaneous coronary intervention providing a temporary drug eluting scaffold resorbed in two to five years. We present two cases of late scaffold thrombosis associated with strut fracture during the period of resorption, at 20 and 24 months following BVS implantation. We propose luminal migration of malapposed struts following strut fracture during resorption as a potential mechanism for late scaffold thrombosis and acute coronary syndrome.
