Anomalous origin of circumflex coronary artery from right pulmonary artery: report of a rare anomaly
DA Ott, DA Cooley, WW Pinsky and CE Mullins
A heretofore unreported anomaly of the coronary arteries in which a large
circumflex artery arises from the pulmonary artery is described. The
circumflex coronary artery in an 8-year-old girl was filled in a retrograde
fashion via collaterals from a dominant left anterior descending coronary
artery, and the right coronary artery was small and nondominant. Successful
surgical correction of this defect was performed by use of total
cardiopulmonary bypass and cardioplegic arrest. The orifice of the
anomalous vessel and detached from the right pulmonary artery and implanted
into the posterolateral aspect of the ascending aorta. Cardiopulmonary
bypass with cardioplegic arrest is recommended for reconstruction of
coronary arterial anomalies with abnormal sites of origin.
