Postinfarction Ventricular Septal Defect With Pseudoaneurysm Repair After Failed Percutaneous Closure

Ventricular septal defect with intramyocardial dissection of the ventricular free wall is a rare complication of myocardial infarction associated with poor prognosis. We describe a patient who developed a ventricular septal defect with intramyocardial dissection of the right ventricular free wall. Initially the patient was successfully stabilized by the placement of a percutaneous closure device. The placement of the device allowed initial hemodynamic recovery of the patient and subsequent definitive surgical repair. This case illustrates the importance of collaboration between interventional cardiologists and cardiac surgeons in the treatment of complex postinfarction ventricular septal defects.
