BACKGROUND: Early 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.OBJECTIVE: Study outcomes of complete AV canal repair.DESIGN: Retrospective, descriptive.SETTINGS: Single institute.PATIENTS AND METHODS: Medical 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 MEASURES: Pre- and postoperative morbidity and mortality.SAMPLE SIZE: 140 patients.RESULT: The 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%).CONCLUSION: The 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.LIMITATION: Retrospective in single institute.CONFLICT OF INTEREST: None.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
