Abstract

Long-term left atrioventricular valvar function was evaluated in 95 of 110 survivors following surgical repair of atrioventricular septal defect between 1975 and 1984. A common or complete form was present in 40 and a partitioned or partial form in 55 patients. The patients have been followed for three to 13 years with a mean of 8.3 years. Pulmonary arterial banding was performed in 17 patients with a common atrioventricular valve prior to complete repair. The left atrioventricular valvar regurgitation was evaluated by clinical examination, Doppler and/or angiography. Three patients required valvar replacement postoperatively. Previous pulmonary arterial banding, pulmonary hypertension or pulmonary-to-systemic flow ratio did not affect the incidence or severity of left atrioventricular valvar regurgitation postoperatively. In this series left atrioventricular valvar regurgitation increased in the early postoperative period but rarely progressed at late follow-up.
