Highlights the importance of careful dissection and adequate myocardial protection during emergency aortic surgery when a rare single coronary artery anomaly is incidentally encountered.
Single coronary artery (SCA) in the absence of other major congenital cardiovascular anomalies is rare. We report an extremely rare case of acute aortic dissection in an octogenarian who had a single left coronary artery with the right coronary artery originating from the distal circumflex. A single ostium was incidentally detected by visual inspection during an operation. We diagnosed the anomaly in detail by postoperative 64-slice multi-detector computed tomography. As we performed an emergency operation, it was difficult to recognize SCA preoperatively. In this situation, it is very important to establish adequate myocardial protection and careful dissection is necessary to avoid iatrogenic injury.
