A case report of anomalous origin of a single coronary artery from the pulmonary artery associated with multiple cardiac malformations.

Anomalous origin of a single coronary artery from the pulmonary artery is exceedingly rare. Clinical and necropsy findings in a 17-month-old boy with anomalous origin of a single coronary artery from the pulmonary artery are described. In our case, no areas of infarction or ischemic changes were found as well as in 4 of the 5 previously reported cases. It is most important that surgical treatment be performed without delay.
