Repair of pulmonary arterial stenosis after Waterston-Cooley anastomosis.

Within the spectrum of neonatal congenital cyanotic heart disease, emergent surgery is often necessary to correct profound pulmonary hypoperfusion. An ascending aorto-to-pulmonary artery anastomosis (Waterston-Cooley) has proved to be the preferred procedure in selected patients. A new technique to correct the occasional resultant pulmonary arterial deformity is presented which is performed concomitantly with definitive intracardiac correction.
