Between February 1991 and October 1994, 29 patients received right heart bovine pericardial valved conduits. Patients' ages ranged from 19 days to 18 years (mean 3.5 years), with 8 patients younger than 1 year of age. Ten patients had truncus arteriosus type II or III, 7 had pulmonary atresia with ventricular septal defect (VSD), 6 had transposition of the great arteries and pulmonary stenosis (PS), 3 had corrected transposition with VSD and PS, 2 had double-outlet right ventricle, and 1 had aortic atresia with normal left ventricle and VSD. Two hospital deaths (6.9%) occurred, but no late deaths. The postoperative serial echocardiographic studies showed a mean transconduit gradient of 16 mm Hg with a range of 2 to 37 mm Hg. All patients are in functional class I. Although the intermediate results are satisfactory, considering the late complications known from others conduits, long-term follow-up is necessary.
