Surgical management of left ventricle outflow tract obstruction in infants with right-dominant unbalanced transitional atrioventricular septal defect poses difficulties. A two-month-old infant with transitional atrioventricular septal defect and complex left ventricle outflow tract obstruction presented in cardiogenic shock. The patient underwent successful biventricular repair. The operative procedure included detachment of the anterior bridging leaflet and resection of its chordal attachments. Septal myectomy was performed with creation of an interventricular communication, followed by patch augmentation of the left ventricular outflow tract and anterior bridging leaflet. The zone of apposition between anterior and posterior bridging leaflets was closed. The repair resulted in effective augmentation of the left ventricular inflow and outflow tracts.

SummaryDuring a 10 year interval, between January 1, 1981 and January 1, 1991, primary repair of atrioventricular septal defect with a common atrioventricular orifice was performed in 95 patients younger than 1 year. Patients with atrioventricular septal defect having two atrioventricular orifices and a small ventricular septal defect, and those with severe hypoplasia of the left ventricle, were not included in the present study. According to the presence of associated anomalies, patients were divided into those with simple forms (72%) and those with complex forms (28%). These included parachute deformity of the left atrioventricular valve (10 cases), multiple muscular ventricular septal defects (5 cases), low-lying infundibular stenosis of the right ventricle (4 cases), obstruction of the left ventricular outflow tract (3 cases), tetralogy ofFallot (2 cases) and hypoplasia of the left ventricle (2 cases).
