Transcatheter closure of large perimembranous ventricular septal defects with inlet to outlet extension with the Amplatzer Vascular Plug-II.

Transcatheter closure of perimembranous ventricular septal defect is an alternative to surgery in selected small to medium defects with a reasonable distance between the defect and the aortic or tricuspid valves. Surgical closure is generally preferred for large defects with an inlet to outlet extension, aortic malalignment, or deficient aortic rim. We report two successful cases of percutaneous closure of large perimembranous ventricular septal defects with inlet to outlet extension using an Amplatzer Vascular Plug-II via a retrograde approach. Transcatheter closure of large perimembranous ventricular septal defect with inlet to outlet extension is feasible and facilitated by the characteristics of the Amplatzer Vascular Plug-II device and the specific implantation technique.
