An alternative method for repair of partial anomalous pulmonary venous connection to the superior vena cava.

The surgical management of 15 patients with partial anomalous pulmonary venous connection (PAPVC) to the high superior vena cava (SVC) is described. This new technique redirects the anomalous pulmonary venous flow into the left atrium through the cardiac end of the SVC, transected and oversewn above the anomalous pulmonary vein or veins, by coaptation of the atrial septal defect (or of the surgically created septal defect in patients with an intact atrial septum) to the intracardiac orifice of the SVC. Normal SVC-right atrial flow is reconstituted by atriocavoplasty to the cephalad portion of the transected SVC. A 31-year-old woman with severe pulmonary hypertension died early in the series; this was the only death. Surviving patients enjoy full activity. Except for one symptomatic SVC obstruction due to technical error (since relieved), this technique has achieved total correction of these congenital defects with marked reduction in the undesirable postoperative sequelae often associated with other methods of repair.
