Considerations in the Surgical Management of Ventricular Septal Defect and Aortic Insufficiency

Abstract

A 23-year-old man presented with progressive exercise-related dyspnea and easy fatiga bility. He gave a history of a murmur of aortic insufficiency since childhood. Cardiac catheterization demonstrated severe aortic insufficiency. At surgery the patient was found to have prolapse of the right coronary cusp into a significant supracristal ventricular septal defect. Repair was carried out with a Dacron patch closure of the septal defect and replacement of the valve with a 29-mm St. Jude valve. The patient recovered uneventfully and is fully active and employed 5 years later. Review of the literature documents that this is an uncommon lesion. The approaches to preoperative diagnosis include transesophageal echo. The management techniques have included ventricular septal defect closure, alone and with valvuloplasty, and septal defect closure with aortic valve replacement. The anatomic and patient characteristics guide selection of the most suitable management of these patients.
