Transcatheter utilisation of lifetech multifunction™ occluder device for closure of perimembranous and muscular ventricular septal defects: first use in North America.

Abstract

Transcatheter closure of ventricular septal defects is considered first-line therapy when anatomically appropriate but is often challenged by proximity to the conduction system in perimembranous defects, or irregular defect shape, especially residual defects that may remain post-operatively. Advancements in device design, however, have allowed for significant improvements in deployment techniques and overall safety. Here we describe the first use of the Lifetech Konar-multifunction™ occluder device in North America, and our specific use of this device to close complex post-operative muscular and a perimembranous-ventricular septal defects in the same patient.
