Major coronary evaginations following implantation of bioresorbable vascular scaffolds – Clinical and OCT characteristics
Highlights
- • Coronary evaginations after implantation of bioresorbable scaffolds are associated with progressive lumen enlargement.
- • Areas with evaginations are associated with higher rates of strut fracture and malapposed struts.
- • The area of scaffolds affected by evaginations increases over time.
Abstract
Background
Coronary evaginations can occur after implantation of bioresorbable vascular scaffolds (BRS) and may be associated with scaffold thrombosis. Aim of this study was to clarify the clinical manifestation, extent and time course of coronary arteryremodeling in vessel segments that develop angiographically detectable evaginations following BRS implantation through optical coherence tomography (OCT) analysis.
