Robotic repair of atrial septal defect with partial pulmonary venous return anomaly: Our 5 year experience

Introduction Partial pulmonary venous return anomalies (PPVRA) were not considered as a good candidate for robotic surgery in early time of robotic cardiac surgery. In this study, we present our experience in patients undergoing robotic atrial septal defect (ASD) and PPVRA surgery. Methods Between November 2014 and January 2020, data of 21 patients underwent robotic ASD with PPVRA was collected. Inclusion criterion was presence of right-sided PPVRA with ASD. All operations were performed robotically. Results The mean age of patients was 26.7 +/- 10.3 years. Seventeen patients (81%) had superior-caval ASD with supracardiac PPVRA and double-patch technique was used. Four patients had inferior-caval ASD with intracardiac PPVRA and single-patch technique was preferred. Cross-clamp time and cardiopulmonary bypass time were 92.8 +/- 29.6 and 127.8 +/- 38.1, respectively. There was no mortality. One patient had atrioventricular-block and required pacemaker. Conclusion Robotic repair of ASD with PPVRA is feasible and effective method as an alternative to conventional surgery.
