Restored Physiological Vasomotion Imitating Intrascaffold Restenosis 3 Years After Bioresorbable Scaffold Implantation

Abstract

Bioresorbable vascular scaffolds (BVSs) have recently been introduced into clinical practice; they have many potential advantages, 1 of which includes restoring physiological vasomotion. It has been shown that the degree of vasomotion is correlated with bioresorption. We present a case of intrascaffold spasm masquerading as restenosis 3 years after implantation, despite the ongoing process of bioresorption: intra-BVS vasospasm should therefore be considered and confirmed by intracoronary nitrate administration.
