 Haemodynamically significant congenital anomalies of the coronary arteries

Isolated/primary—without CHD

• Anomalous origin of accessory coronary arteries from the pulmonary artery (ALCAPA, ARCAPA)

• Ectopic origin of the coronary arteries from aortic sinus

• Absence of a coronary artery

• Congenital coronary artery fistula

Secondary—with CHD

• PA + IVS

• AA + MS

AA, aortic atresia; ALCAPA, anomalous origin of the left coronary artery from the pulmonary artery; ARCAPA, anomalous origin of the right coronary artery from the pulmonary artery; CHD, congenital heart disease; IVS, interventricular septum; MS, mitral stenosis; PA, pulmonary atresia.
