Repair of anomalous pulmonary venous connection to the superior vena cava

Complex forms of anomalous pulmonary venous connection to the superior vena cava (SVC) can be difficult to correct surgically. Since 1987, 11 patients have undergone repair of anomalous pulmonary venous connection to the SVC by diversion of the pulmonary venous drainage to the left atrium using a baffle with division of the SVC and reimplantation on the right atrial appendage to restore normal systemic venous drainage. Total anomalous pulmonary venous connection was present in 3 patients and partial anomalous pulmonary venous connection, in 8. All patients are alive and asymptomatic at a mean follow-up of 2.3 ± 1.4 years. Postoperative echocardiograms (8 patients) revealed pulmonary venous obstruction requiring reoperation in 1 patient. No patient has clinical evidence of SVC obstruction, and all are in sinus rhythm. This is a safe and effective technique for repair of complex forms of anomalous pulmonary venous connection to the SVC, and the incidence of postoperative venous obstruction and rhythm disturbances is low.
