[Anomalous origin of coronary arteries in adults].

In lack of structural congenital heart disease, anomalous origin of a coronary artery is rare with an angiographic prevalence of approximately 1%. The prognosis depending on anatomical features, initial course of coronary ectopic vessel is important to be considered. Although some anomalies are associated with sudden death, the majority are simply incidental anatomic findings. In patients with high-risk coronary anomalies, the treatment is not clearly codified. Large-scale prospective multicenter studies are needed to define recommendations in the future.
