An anomalous course of a coronary artery, a type of congenital coronary artery anomaly, can be merely a benign and incidental finding, but can also be life threatening, depending on where the artery runs.
In the majority of cases, the aberrant artery has what is referred to as a benign course. Some however pass between the aorta and the main pulmonary artery (so-called interarterial course). When this is the cases, and especially during physical activity, the artery is compressed and flow within it compromised. For this reason this condition is called malignant.
This can result in ischaemia, arrhythmias or sudden death.
Treatment and prognosis
If untreated the prognosis is severe. An interarterial course requires surgical repair.
