Abstract: Objective To summarize the clinical outcomes and experience of surgical treatment for patients with complete atrioventricular septal defect (CAVSD) above the optimal age for surgery. Methods We retrospectively reviewed clinical data of 163 simple type CAVSD patients less than 7 years who underwent operations in Fuwai Hospital from 2002 to 2013. The patients were divided into a normal group (n=84, including 37 males and 16 females with an average age of 7.6±2.7 months) and an over-age group (n=79, including 30 males and 49 females with an average age of 34.6±19.6 months) according to whether the age was more than 1 year. Results The average aortic cross clamp time (88.3±24.4 min vs. 106.1±35.4 min, P<0.001) and cardiopulmonary bypass time (123.6±31.1 min vs. 142.6±47.1 min, P=0.003) were statistically different between the two groups. During the follow-up period (the normal group 53.3±43.9 months, the over-age group 57.2±48.2 months), there was no statistical difference in all-cause mortality (10.7% vs. 8.9%, P=0.691), the incidence of moderate or severe left atrioventricular valve regurgitation (16.7% vs. 21.5%, P=0.430) and reintervention rate (3.6% vs. 0.0%, P=0.266) between the two groups. No left ventricular outflow tract obstruction and complete atrioventricular block occurred in both groups. Conclusion For CAVSD children above the optimal age, rational surgical treatments can also achieve satisfying results.
