[Jatene procedure for the intermediate type between original Taussig-Bing malformation and posterior transposition of the great arteries: a case report].

A successful Jatene procedure (Lecompte modification) in a 8-month old boy with the intermediate type between the original Taussig-Bing and the posterior transposition of the great arteries (p-TGA) is described. The aorta was located posterior to the right of the pulmonary artery (PA) which overrode the interventricular septum. There was no fibrous continuity between aortic and atrioventricular valves. In the original Taussig-Bing, intraventricular rerouting is applicable because of malaligned infundibular septum. However, in our case which was similar to p-TGA, the infundibular septum extending anteriorly as far down as the anterior papillary muscle, was almost aligned to the interventricular septum, so that intraventricular rerouting is not applicable but arterial switch operation is preferable. Hence, the primary interventricular foramen was enlarged by the wedge resection and the secondary interventricular foramen was closed using pericardial patch through PA. The continuity of PA was reestablished anterior to the new aorta. The left half of distal orifice of PA was suture-closed to shift the site of anastomosis rightwards to avoid kinking and compression on the coronary arteries. Postoperative catheterization demonstrated no pressure gradient between left ventricle and aorta.
