title: [Surgical treatment of ventricular septal defect in the first year of life].
abstract: Forty six infants with a large ventricular septal defect (VSD) underwent surgical treatment during the first 12 months of life. Forty three patients ranging in age from 3 to 12 months (mean age 10.4 months) and weighting from 3.0 to 8.2 kg (mean weight 6.8 kg) had primary surgical closure of their VSD. All infants were below the third percentile for weight preoperatively. In 40 patients (93%) the defect was closed through the right atrium. Three patients (7.0%) died in the early postoperative period. Surgically induced heart block occurred in one patient (2.3%). Late results were assessed in 29 surgical survivors (mean follow-up 26 months). There was no late mortality. Relief of congestive heart failure was prompt in all patients following closure of VSD. Right bundle branch block with left anterior hemiblock developed in 5 patients (17.2%), and right bundle branch block alone in 10 patients (34.5%). Three patients (mean age 4.3 months, mean weight 2.7 kg) underwent initial palliative pulmonary artery banding (PAB). There were no operative or late mortality. Closure of VSD and pulmonary artery debanding was performed in two of these patients, with no mortality. Prior to intracardiac correction the pulmonary artery pressure distal to the band was normal; no band related complications were found. Early primary closure is the treatment of choice for symptomatic infants with large VSDs. In particular circumstances, however, PAB may provide effective palliation.
