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.
Résumé
Les échafaudages vasculaires biorésorbables (EVB) ont récemment fait leur entrée dans
la pratique clinique. Ces dispositifs pourraient offrir de nombreux avantages dont
l’un est le rétablissement de la vasomotricité physiologique. Une corrélation a été
démontrée entre le degré de vasomotricité et la biorésorption. Nous présentons ici
un cas de spasme intra-échafaudage déguisé en resténose trois ans après l’implantation,
malgré la biorésorption constante. Il convient donc d’envisager la possibilité d’un
vasospasme intra-EVB et de confirmer sa présence par l’administration intracoronarienne
de nitrate.
