title: Doubly committed subarterial ventricular septal defect with severe aortic regurgitation: the "two-patch" technique.
abstract: Doubly committed subarterial ventricular septal defect complicated by severe aortic regurgitation caused by a prolapsed aortic cusp still represents a challenging surgical problem. We report on our "two-patch" technique, were the ventricular septal defect is closed through the aortic valve by a patch anchored to another patch through the prolapsed cusp. This second patch is pulled up with the prolapsed cusp and is then fixed to the aortic wall. Since May 1990, 15 patients with a mean age of 12 years underwent repair of this cardiac malformation with the "two-patch" technique. The aortic regurgitation was severe in all patients. All patients survived. In a mean follow-up of 10 years, two patients were successfully reoperated for progression of the aortic regurgitation. All the remaining patients were in NYHA functional class I. In conclusion, the "two-patch" technique is simple, easily reproducible, and can be a valid surgical option for this complex cardiac malformation.
