Late structural discontinuity after bioresorbable vascular scaffold implantation in patients with in-stent restenosis

Bioresorbable vascular scaffolds (BVS) allow the treatment of coronary lesions by offering vascular support and antiproliferative drug release without the need to implant a permanent metal layer in the coronary vessel. A problem occasionally observed during follow-up is late fracture or late structural discontinuity1,2. Although severe BVS dismantling has been associated with an increased risk of late BVS thrombosis, the implications of this phenomenon still remain uncertain1,2. The use of BVS in patients with in-stent restenosis (ISR) has ...
