The relief of cyanosis in patients with right-sided cardiac defects with or without associated defects of the septum or great vessels usually has been by an arterial anastomotic procedure.9 The Potts and Blalock operations, although generally accepted, frequently are followed by heart failure or death. Results are better in patients beyond the immediate newborn period.13 These procedures are preferred for tetralogy of Fallot, but further evaluation is needed for the best palliation of other types of cyanotic heart disease in newborn infants. Such cyanotic lesions include tricuspid atresia, tricuspid stenosis, pulmonary atresia, Ebstein's anomaly, transposition of the great vessels, and complicated cardiopathies with decreased pulmonary blood flow.
More recently, superior vena cava-pulmonary artery shunt has been proposed in the treatment of cyanotic heart disease.5,8,10 The supposed advantages of venous shunt as compared to a systemic arterial shunt are related to avoidance of heart failure and greater relief
