Single coronary artery is a rare congenital anomaly in which a single artery arises from the aorta. The anomalous single trunk supplies blood to the entire heart. It is classified according to its origin, branching pattern, and course. The presence of a single coronary artery can be an isolated finding or associated with additional cardiac anomalies. Diagnosis is important because of therapeutic implications, although it is an incidental finding. As with any other coronary anomalies, its recognition is more common today because of increasing use of multidetector CT. The objective of this article is to review the classification of single coronary artery anomaly and its clinical significance and to illustrate the imaging findings on multidetector CT.
