title: [A successful arterial switch operation for the transportation of the great arteries with posterior aorta--with special reference to its anatomical features and possibility of the indication of the Jatene procedure].
abstract: A five months old infant with the transposition of the great arteries with posterior aorta undergoing arterial switch operation is reported. A pre-operative diagnosis of the transposition of the great arteries with posterior aorta, subarterial ventricular septal defect, anterior pulmonary artery, bilateral conus and fibrous continuity between aortic and mitral valve was made. This diagnosis was confirmed by the open heart surgery. The ventricular septal defect was subaortic from the transected aortic aspect, and the infundibular and trabecular septum was aligned. For these reasons, this subarterial ventricular septal defect was easily closed transaortically. The right coronary artery arose from the left sinus and the left coronary artery from the posterior sinus, so the coronary arterial pattern of this patient was a Shaher type 9. And in addition, another small ostium located in the left sinus gave rise to an additional small branch. Translocation of the coronary arteries was performed. The new pulmonary trunk was reconstructed to the right pulmonary artery so as not to compress the coronary artery and distort the great arteries. This patient was restudied three months after the repair. The right to left ventricular systolic pressure ratio was 0.42 and no pressure gradient was present between the right ventricle and the right pulmonary artery. But a moderate aortic regurgitation was detected. This was caused by deformity of the aortic sinus of valsalva. Only 28 patients with the transposition of the great arteries with posterior aorta were reported in the literature, but there were no reports on the successful surgical treatment for its rare anomaly, to our knowledge.(ABSTRACT TRUNCATED AT 250 WORDS)
