A new operation for ventricular septal defect with aortic incompetence.

Abstract

Two boys, 10 years of age, with ventricular septal defect and severe aortic insufficiency were treated using a new method. An autograft of anterior pulmonary artery wall and the adjacent leaflet and subpulmonary muscle was excised. The excised pulmonary artery segment was used to replace the prolapsed right coronary cusp, and the autograft muscle was used to close the ventricular septal defect. The right ventricular outflow tract and pulmonary valve were repaired using an autologous pericardial patch with an autologous single cusp. The results in both cases were satisfactory.
