Totally robotic repair of atrioventricular septal defect in the adult

Background: Atrioventricular septal defect (AVSD) accounts for up to 3 % of congenital cardiac defects, which is routinely repaired via median sternotomy. Minimally invasive approach such as endoscopic or robotic assisted repair for AVSD has not been reported in the literature. With the experience with robotic mitral valve surgery and congenital defect repair, we initiated robotic AVSD repair in adults. Case Presentation: In this report, we presented three cases of successful repair of partial and intermediate AVSD by using da Vinci SI surgical system (Intuitive Surgical, Inc., Sunnyvale, CA). Conclusions: Totally robotic AVSD repair via right atriotomy could be safely performed in adults and it may provide superior cosmesis with the comparable surgical outcome of the repair via sternotomy.
