[en] A 7-year-old boy developed increasing cyanosis after a total cavopulmonary connection with a 3 mm fenestration in the baffle. Catheterisation performed 4 years and 7 months after the operation showed reopening of a left superior caval vein draining into the pulmonary venous atrium. Due to the large size of the left superior caval vein, and the absence of intrinsic stenosis, we chose to use an Amplatzer ductal device to occlude the reopened vein. The procedure was safe and successful.
