BackgroundEarly surgical management of complete atrioventricular (AV) canal defect is the optimal treatment option. Since the published evidence on outcomes is inconclusive, we retrospectively studied the outcomes of patients in our institution.ObjectiveStudy outcomes of complete AV canal repair.DesignRetrospective, descriptive.SettingsSingle institute.Patients And MethodsMedical records of patients under 2 years of age who underwent complete AV canal repair from January 2004 to December 2014 were retrospectively reviewed.Main Outcome MeasuresPre- and postoperative morbidity and mortality.Sample Size140 patients.ResultThe median (IQR) age at the time of surgery was 5.4 (3.9-8.2) months. Down syndrome was diagnosed in 98 (70%) of patients. AV valve regurgitation was found preoperatively in 129 (92%) and postoperatively in 135 (96%) patients. There was a significant association between preoperative pulmonary hypertension and the development of pulmonary hypertension in the postoperative period ( P=.04). Thirty-three patients needed reoperation. Arrhythmia was found in 19 patients, 16 of whom required pacemaker insertion. Seven patients died (5%).ConclusionThe presence of preoperative and postoperative AV valve regurgitation was common in this cohort but did not significantly affect patient survival. Our findings suggest an acceptable outcome for repair of complete AV septal defect with few complications postoperatively.LimitationRetrospective in single institute.Conflict Of InterestNone.
