Left ventricular pseudoaneurysm after perventricular ventricular septal defect device closure.

Perventricular ventricular septal defect (VSD) closure has been adopted as a therapeutic option for selected patients with muscular VSDs. This technique may combine some of the advantages of surgical and interventional techniques. Complication rates have been low: only one case of procedure-related left ventricular (LV) pseudoaneurysm has been documented. We report the surgical repair for a LV pseudoaneurysm after perventricular VSD device closure.
