Total anomalous pulmonary venous return with associated patent ductus arteriosus. Two cases with successful correction.

A large patent ductus arteriosus associated with total anomalous pulmonary venous return results in a unique hemodynamic pattern, and long-term survival has been rare. Two patients, aged five and 18 years, underwent successful surgical repair of supracardiac total anomalous pulmonary venous return and an associated large patent ductus arteriosus. The association of the Noonan syndrome in the 18-year-old woman is of additional interest.
