Catheter management of occluded superior baffle after atrial switch procedures for transposition of great vessels

We present successful catheter intervention in 4 patients with total occlusion of the superior baffle after an atrial switch procedure. A transseptal needle (in addition to the transhepatic route in 1 patient with known occluded femoral veins) was used to open the occluded segments and place stents. Additionally, we report the regression of multiple systemic-to-pulmonary venous fistulas that developed as a result of the occluded baffle.
