    Abstract:
    BACKGROUND: Surgical repair of complete atrioventricular septal defect (CAVSD) is a well-established procedure performed on young children. Our hypothesis is that with modern techniques, the current risks of CAVSD repair in children aged younger than 3 months and in children older than 3 months are equal. METHODS: This was a retrospective review of 65 infants and children with a mean age of 10.9 months (range, 1 month to 15.5 years) who underwent CAVSD repair from 1990 to 2004. Twenty-six repairs (40%) were done on or before 3 months of age (group A) and 39 repairs (60%) were done after 3 months of age (group B). In all patients, the ventricular septal defect was repaired with an individualized approach according to each patient's specific anatomy: direct suturing without a patch, interposition of a small pericardial patch with a running suture, or both. The atrioventricular commissure was closed with interrupted sutures, and all atrial defects were closed with a pericardial patch. Data were analyzed using the chi2 analysis and the Fisher exact test. RESULTS: Three hospital deaths occurred (<30 days), 2 in group A and 1 in group B (7.7% vs 2.6%, respectively, p = 0.33). One death in group A occurred during another noncardiac surgery. Early reoperation (<1 year of initial surgery) for residual ventricular septal defect or significant mitral regurgitation, or both, occurred in 3 group A patients and in 4 group B patients (11.5% versus 10.3% respectively, p = 0.68). CONCLUSIONS: These results suggest that repair of CAVSD defects in children 3 months of age or younger had similar outcomes compared with those who underwent surgical repair after 3 months of age.
