Catheter closure of perimembranous/membranous ventricular septal defects using the Amplatzer occluder device

Perimembranous ventricular septal effects (PMVSDs) are the most common congenital cardiac defects of clinical importance. During the last decade, transcatheter closure of PMVSDs has been attempted using various occluders with variable success. This article reviews the existing literature and our experience with transcatheter closure of PMVSDs with the new Amplatzer occluder device.
