Totally endoscopic robotic repair of coronary sinus atrial septal defect with concomitant tricuspid annuloplasty.

Abstract

Background: The coronary sinus type of atrial septal defect is rare. Standard treatment typically involves intracardiac repair using conventional sternotomy or thoracotomy incisions; however, robotic technology can offer a feasible alternative due to its ability to provide a high-quality surgical view of this anomaly.

Case presentation: A 72-year-old man presented with asymptomatic atrial septal defect. Echocardiography revealed a direct communication between the left atrium and CS with left-to-right shunt flow and a Qp/Qs ratio of 2.1:1. The coronary sinus type of atrial septal defect was indicated for the totally endoscopic robotic repair considering few comorbidities. We present a successful robotic repair of coronary sinus atrial septal defect with concomitant tricuspid annuloplasty via the right atrium, properly identifying the boundary between the mitral annulus and coronary sinus through a high-quality surgical view.

Conclusion: Robotic repair can serve as a viable and therapeutically effective alternative for cases of coronary sinus atrial septal defect with concomitant tricuspid annuloplasty.
