Objective : To assess the function of the left atrioventricular valve (LAW) following surgical repair of complete atrioventricular septal defect (CAVSD) and find out the possible risk factors for development of left atrioventricular valve regurgitation (LAVVR). Methods : Over a ten-year period, 105 patients with the diagnosis of CAVSD underwent surgical repair us­ing the two-patch technique at our in­stitution. According to our inclusion criteria, only 97 patients were includ­ed in this study. Patients were evalu­ated preoperatively by full history tak­ing, physical examination and 2-D echo-Doppler evaluation. Intraopera-tive transesophageal ecnocardiogra-phy was performed in all patients. Results : The included 51 boys and 46 girls. Age ranged from 70 to 517 days (mean of 182 ± 10.5). Body weight ranged from 3.8 to 8.2 Kg. (mean of 4.6 ±0.15). Down's syndrome was present in 71 patients. Associated cardiac defects were present in 51 patients. Sixty-six patients had Rastelli type A, 6 had type B, and 25 had type C. The LAW cleft was completely closed in 50, partially closed in 21 and left without closure in 26 patient. Additional annuloplasty was done in 13 patients. At discharge, the degree of LAW
