Transcatheter closure of iatrogenic perimembranous ventricular septal defect after aortic valve and ascending aorta replacement using an Amplatzer membranous ventricular septal occluder.

Iatrogenic perimembranous ventricular septal defect is a rare complication after surgical replacement of the aortic valve, and so transcatheter closure of such a defect is not a routine procedure. We report the successful closure of an iatrogenic perimembranous ventricular septal defect which occurred after the replacement of the aortic valve and ascending aorta.
