Figure 7. Transposition of great arteries after Senning operation

Figure 7. MRI from an adult with transposition of the great arteries after a Senning operation. A severe pulmonary venous baffle obstruction is identified (arrow). This stenosis was successfully dilated with stent placement during a hybrid procedure and the mean gradient across the stenosis was reduced from 14 mm Hg to 3 mm Hg.
