Ventricular Pseudoaneurysms After Perventricular Closure of Ventricular Septal Defect

Perventricular ventricular septal defect closure has become an accepted method for treatment of some muscular and perimembranous ventricular septal defects. This report describes the case of a child who had left ventricular pseudoaneurysms after perventricular closure of a ventricular septal defect performed at 3 months of age. At 18 months, the ventricular pseudoaneurysms were closed surgically. Ventricular trauma from guidewire use during device placement was thought to be the cause. The potential for injury to the left ventricular free wall should be borne in mind and sought with serial imaging during and after perventricular septal defect closure.
