Abstract
- An adequate location of the reimplanted coronary arteries is one of the most important prognostic factors for an arterial switch operation for treating TGA (transposition of great arteries). We report here on a case of malposition of the reimplanted coronary artery in a 14-year-old boy who had undergone an arterial switch operation. He had chest pain and dyspnea on exertion. The imaging study showed that the ostium of the left main coronary artery, which was between the neo-pulmonary artery and the neo-aorta, was compressed by the great arteries. We excised the left main coronary artery with a button incision from the aorta and reimplanted it on the left lateral side of the aorta. The patency of the left main coronary artery os after the operation was good and it was not compressed by the surrounding arteries.
