Intracardiac baffle repair of complex completely unroofed coronary sinus with persistent left superior vena cava in an adult.

A 35-year-old woman presented with dyspnea on exertion. The diagnosis was unroofed coronary sinus with persistent left superior vena cava and atrial septal defect. She underwent total correction with the intracardiac baffle technique by using an interatrial flap and autologous pericardial patch. Her clinical course was uneventful and markedly improved after the surgery.
