[Sudden cardiac death and anomalous connections of the coronary arteries: What is known and what is unknown?].

Some anomalous connections of the coronary arteries may be associated with a risk of sudden cardiac death. In opposite with others cardiac diseases at risk of sudden cardiac death, the relationship between these congenital abnormalities and the risk of sudden cardiac death are not well understood. A correction of the anomaly is generally indicated after an aborted sudden cardiac death. Primary prevention strategy after the discovery of an anomaly at risk is debated. Even if the absolute risk of sudden death is very low, a pre-participation screening in young athletes may be discussed due to a non-rare incidence.
