Right ventricular outflow construction without cardiopulmonary bypass.
Establishment of right ventricular-pulmonary arterial continuity without the use of cardiopulmonary bypass was undertaken in 36 patients with different anomalies associated with pulmonary atresia or severe stenosis. Hospital mortality was 11% with no late death. Fourteen of the 27 individuals with pulmonary atresia, ventricular septal defect, and hypoplastic confluent pulmonary arteries had adequate angiographic follow-up, which demonstrated significant pulmonary artery enlargement. Five patients underwent total correction, two after unifocalization operations to establish lobar pulmonary arterial continuity. Symmetric growth of the left and right pulmonary artery was not achieved. However, the enlargement was adequate for potential final repair in all the patients with an unrestricted outflow tract.
