Freedom From Stent Fracture-Related Complications of Vascular Longitudinal Remodeling in a Patient With Heart Failure and a Degraded Bioresorbable Vascular Scaffold.

Abstract

Because vascular geometric change during the long-term process of cardiac chamber remodeling in heart failure is usually unpredictable after coronary stenting, the risk of acquired metallic stent fracture can persist. This rare but possible complication could be minimized with the implantation of bioresorbable vascular scaffold because of its unique properties. Here, the authors report on 1 patient with heart failure who received optical coherence tomography evaluation between 3 and 3.5 years after bioresorbable vascular scaffold implantation. Measurement of the discernible struts of bioresorbable vascular scaffold provided evidence of coronary longitudinal remodeling without serious risk of complications related to metallic stent fracture resulting from cardiac remodeling.
