Abstract: Background: We assessed the post-operative result of patients who went through surgical repair of partial atrioventricular canal defect and quantify the short-term outcome. Objective: To find out the Post-operative outcome of Partial Atrioventricular Canal Repair. Materials and Methods: This is a perspective study, in our center, where we included children undergoing surgical repair of Partial AV canal defect from 2012 to 2019. Total 70 patients were enrolled in this study. We performed the intracardiac repair and monitor these patient whether they have developed mitral valve regurgitation, any residual defect and immediate post-operative complications and reappearance of symptoms. Results: During the study period 70 patients were selected and performed intracardiac repair of partial av canal defect and along with mitral valve cleft repair. The group for this analysis included 70 patients (43 partial; 27 transitional). Male 40 (57.1%) and female were 30 (42.9%) (Figure 1). Weight z-scores at surgery ranged from −4.8 to 4.2 (median −0.66). Patients with partial AVSD underwent repair significantly later than patients with transitional defects, but their weight z-scores were similar. The median age of repair was 2.8 years.There were no operative death only 1 death after 1 month post operatively due to infective endocarditis, and 2 post-operative wound infection. During our one year follow-up, no reoperation was done. However, 10 patients were detected mild to moderate left ventricular outflow tract obstruction, with minimal symptoms, may require reoperation in future. No patient had post-operative pacemaker implantation. 4 patients were detected mild to moderate mitral valve regurgitation, may need surgery in future. Mean hospital stay was 9 ±2 days. Our average follow-up periods were 12 months. Conclusion: Intracardiac repair of partial atrioventricular canal defect is quite good at the median age of 2.8 years with no increased in mortality, re-operation and other complications which were reveal with one year follow-up. Patients will be needed to monitor more to order to quantify in the long-term outcome.
