Left Anterior Mini-Thoracotomy for Adult Complicated Subarterial Ventricular Septal Defect

Lack of consensus remains for the minimally invasive surgical repair of adult subarterial ventricular septal defects, and the technique has rarely been reported for cases complicated by other cardiac anomalies. We describe a left anterior mini-thoracotomy through the third intercostal incision in an adult woman for combined subarterial ventricular septal defect repair and right ventricular outflow tract obstruction relief. We consider this minimally invasive technique a balanced approach for correction of a complicated subarterial ventricular septal defect in adults.
