[Correction of tetralogy of Fallot in patients with a single pulmonary artery].

2249 patients underwent correction of tetralogy of fallot in our department. 23 of them were with unilateral absence of pulmonary artery, 19 absence of the left pulmonary artery, 4 absence of the right pulmonary artery. The age at operation ranged from 4 to 21 years. Valve-containing conduits were used in 9 patients and right ventricular outflow patch in 14 patients. There were two operative death who both had hypoplasia of the left ventricle. All survivors had good early and late results. Outflow patch with a single valve should be used in tetralogy of fallot with a single pulmonary artery and pulmonary valve ring stenosis. Aorticvalved homograft conduit is suit for the patient with anomalous coronary or pulmonary atresia.
