a, b,c: Preoperative imaging: Two-dimensional transthoracic echocardiogram(a) and a computed tomography scan (coronal view) showing the origin of both arterial trunks from the right ventricle and the potential baffle from the left ventricle to the aorta (yellow line). This view illustrates the challenge of creating the baffle without obstructing either the left ventricle to aorta pathway (red line) or the right ventricle-to-pulmonary artery pathway (blue line) (a,b). Three-dimensional visual model with a cut in the free wall of the right ventricle, showing the tricuspid valve, the location of the interventricular communication, and the positions of the aorta and pulmonary trunk. The presence of bilateral infundibula creates the impression of remoteness of the interventricular communication, but the communication is routable to the aorta, as demonstrated by the proposed yellow suture lines (c)
