    Abstract:
    Twenty five infants with truncus arteriosus underwent complete surgical correction in the first year of life between January 1984 and June 1990 at Marie Lannelongue Hospital. All had cardiac failure and pulmonary hypertension. Another severe cardiac malformation was present in 6 cases. Complete repair was carried out under cardiopulmonary bypass with moderate hypothermia. After closing the ventricular septal defect the continuity of the right ventricle and pulmonary artery was reestablished by a valved Dacron conduit with a bioprosthesis (13 patients), by an autologous pericardial conduit with the same type of prosthesis (5 patients), by a valveless conduit (1 patient) or by direct insertion of the pulmonary artery (6 patients). Eight children (32%) died shortly after surgery. Seventy one per cent of children operated in the first month of life died compared with only 17% of those operated after one month of life (p less than 0.05). The seventeen survivors have been followed up for an average of 21 +/- 22 months. Three secondary deaths were observed at 33 days, 2 and 10 months after surgery: the first child died of left ventricular failure and pulmonary vascular disease related to the complexity of the associated cardiac malformations; the other 2 deaths were unexpected. The one and three year survival rate is 54%. Pulmonary stenosis with a systolic pressure gradient of more than 30 mmHg was found in 7 patients of whom 6 had valved Dacron conduits (p less than 0.01). One child was successfully operated 60 months after the total correction and another child is on the waiting list for reoperation 69 months after the total correction.(ABSTRACT TRUNCATED AT 250 WORDS)
