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$\pm$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.
