Successful treatment of tetralogy of Fallot with pulmonary atresia using a pulmonary homograft.

A 13-year-old boy with tetralogy of Fallot and pulmonary atresia after a Waterston and Blalock-Taussig shunt underwent successful repair using a cryopreserved pulmonary homograft as a valved extracardiac conduit. Aortic transection gave a good operative field for pulmonary angioplasty and closure of the Waterston anastomosis. The cryopreserved pulmonary homograft provided excellent handling characteristics. The postoperative course was good, and postoperative echocardiography showed good function of the valved conduit.
