Finally, a 29-mm Edwards Sapien XT prosthesis was positioned within the stent (Figures 1A,B show baseline pulmonary regurgitation on transesophageal echocardiography and final result on fluoroscopy, respectively).

A preoperative computed tomography scan was performed, and it demonstrated a severely dilated right ventricle (end-diastolic diameter of 68 mm) and a severe stenosis at the distal end of the baffle (Figure 2A). The final result is shown in Figure 2B.
