Repair of a postinfarct ventricular septal defect on the beating heart. Surgical considerations.

Postinfarct ventricular septal defect (VSD) still remains associated with a high mortality and morbidity. Despite the development of modern surgical techniques and medical care it continues to be a difficult therapeutic challenge. This report describes a case of a 70-year-old female patient, who presented with a postinfarct VSD after having anterior wall infarction. She presented with left heart failure, pulmonary hypertension and left to right shunt of 78% (Qp/Qs=4.3). The patient was operated on using cardiopulmonary bypass on the beating heart. The closure was performed with a Dacron-patch and a single bypass to the diagonal branch using the left internal thoracic artery. Postoperatively the patient did well and was discharged in good condition on the 13th postoperative day. We conclude that postinfarction VSD can be repaired on cardiopulmonary bypass avoiding cross-clamping. This method is helpful for the outcome as well as for the early postoperative recovery of elderly patients.
