Surgical management of aortopulmonary window.

Abstract

Aortopulmonary window is a rare anomaly, and a variety of surgical techniques have been described for its closure. We treated 6 infants with aortopulmonary window between 1993 and 1995. Three had associated type A interrupted aortic arch, and another had a muscular ventricular septal defect. The diagnosis was made by echocardiography, confirmed by cardiac catheterization in 4 infants. In 1 very sick neonate with interrupted arch, diagnosis of the window was considerably delayed. In 4 patients, we closed the window by using a flap of pulmonary artery, which was reconstructed without using a patch. In 2 neonates with interrupted arch we anastomosed the mobilized descending aorta directly to the aortic defect of the aortopulmonary window, closing the pulmonary artery with a pericardial patch. There were no hospital deaths, and all patients are in New York Heart Association functional class I at a mean follow-up of 30 months. Echocardiography shows no significant distortion of the great vessels. The techniques described achieve excellent results using only autologous tissues with the potential for normal growth.
