Coronary artery anomalies (or malformation of coronary vessels) are congenital abnormalities in the coronary anatomy of the heart. By definition, these abnormalities are variants of anatomy occurring in less than 1% of the general population. They are often found in combination with other congenital heart defects. Many coronary anomalies don't cause symptoms and are recognized only at the time of autopsy.

They can be associated with sudden death. The real risk of death or the best way to treat these patients is not yet known. The Congenital Heart Surgeons' Society has started a long-term ongoing study called anomalous aortic origin of a coronary artery (AAOCA) to identify the best way to treat this defect.
