Abstract A new corrective operation for truncus arteriosus without the use of an extracardiac conduit was performed in seven patients with truncus type I (six patients) or type II (one patient) aged from 2 to 9 months. The common truncus arteriosus was septated with a patch into aortic and pulmonary segments and the ventricular septal defect was closed through a ventriculotomy. A direct anastomosis between the pulmonary arteries and the right ventricle was performed, the anterior wall being constructed with a patch with a monocusp valve. There was one death in the immediate postoperative period. In the surviving six patients the postoperative right ventricular/left ventricular peak systolic pressure ratio was less than 0.51 in five and 0.60 in one with a residual ventricular septal defect. All are in functional class I between 1 and 14 months after the operation. On the basis of these results, we propose this technique for patients with truncus type I or II in the first year of life.
