Large ventricular septal defect (VSD) repair has been performed in 43 infants under two years of age. Twostaged repair was done for 11 infants and the primary definitive repair for the remaining 32. One hospital death occured among the 43 infants. Postoperatively, the incidence of cathecolamine dosing was, significantly higher, and a prolonged mechanical ventilation was required in the infants under 12 months (Group I), compared to those over 12 months of age (Group II). Regression of pulmonary hypertension after repair was similarly achieved in the two groups. Complete right bandle block tended to occure more frequently in Group I. Exhocardiographic evaluation of the left ventricular function revealed that left ventricular diastolic dimension and ejection fraction returned within normal limits one or two years after surgical repair in both groups. These data suggest that eraly surgical repair for VSD in the first two years of life is an appropriate surgical treatment where satisfactory clinical results can be expected.
