Abstract

BACKGROUND: In this study, we reviewed our early and long-term surgical results of complete atrioventricular septal defect during the last 16 years at our hospital.
MATERIALS AND METHODS
Between April 1986 and March 2002, 73 patients with complete atrioventricular septal defect underwent total correction without preceding palliation. Age at repair ranged from 2 to 85 (median age, 7) months, and weight ranged from 3 to 22 (median weight, 5.9)kg. Follow-up was complete with a mean duration of 69+/-51 months.
RESULTS
Overall operative mortality was 16.4%(12) with 3 late deaths. One, 5, and 10 year actuarial survival rates were 96.3%, 94.2%, and 94.2% respectively. Sixteen of 61 (22.2%) operative survivors have undergone reoperation for postoperative mitral regurgitation or left ventricular outflow tract obstruction (LVOTO). Freedom from mitral reoperation at 1, 5, and 10 years were 87.8%, 72.4%, and 57.8% and freedom from LVOTO at 1, 5, and 10 years were 98.2%, 86.3%, and 83.2% respectively. SUMMARY: In this study, we found that our early surgical results improved with quite an acceptable long-term outcome. Close observation of remaining mitral regurgitation was necessary. A precise evaluation of the atrioventricular valve morphology, a meticulous surgical technique, and the adequate postoperative management are mandatory for the excellent results.
