Sudden cardiac death due to anomalous origin of the right coronary artery: a case report in a child.

Congenital coronary anomalies constitute a statistical incidence of 0.3–0.8% and represent 0.1–2% of all congenital cardiac conditions worldwide. If we consider the anomaly originating of the right coronary artery from the left Valsalva sinus, the prevalence from autoptic studies is reduced to 0.026%. Whereas in angiographic studies, incidence of anomalous origin of right coronary from the left sinus Valsalva changes in different populations.. Results of these studies demonstrated that anomalies are uncommon and frequently associated with sudden death. Most coronary anomalies did not result in signs, symptoms, or complications, and usually were discovered as findings at the time of autopsy.
