Anomalous coronary arteries coursing between the aorta and pulmonary trunk: clinical indications for coronary artery bypass.

Coronary arteries of anomalous origin with subsequent coursing between the aorta and pulmonary trunk can cause ischaemia, infarction or sudden death. However, reports of surgical correction are sparse due to the rarity of ante-mortem diagnosis. We report two cases in which symptoms were related to anomalous origin of a non-atherosclerotic coronary artery. Surgical repair was performed to prevent sudden death or recurrent ischaemia.
