Late results of pulmonary ventricle to pulmonary artery conduits.

The development of the extracardiac conduit has been one of the greatest advances in cardiac surgery. Conduits have decreased the mortality rate of several standard operations and have made possible the correction of numerous complex congenital cardiac anomalies that previously were uncorrectable. However, the ideal conduit has not yet been developed. We have reviewed the long-term (16 to 29 years) results of our early experience with this technique.
