Single coronary arteries are rare (incidence 0.03-0.07%), with a higher incidence in patients with congenital heart disease (in particular truncus arteriosus and pulmonary atresia). They occur when there is a single ostium arising from the aorta with no ectopic ostia. There is a wide variety of courses and configurations of the coronary arteries.
