Right Coronary Artery Arising from the Pulmonary Trunk

Abstract

The prevalence of coronary artery anomalies is reported to be around 0.3-1%. An anomalous origin of the right coronary artery (RCA) is a rare condition but may lead to myocardial ischemia. and sudden death. Diagnosis is mainly made by conventional. coronary arteriography. Nowadays, multislice computed tomography is a new noninvasive imaging technique with excellent: spatial resolution which can detect the origin and course of an. anomalous coronary vessel. Here we report on a 67-year-old woman with an anomalous origin of the RCA arising from the pulmonary trunk. The anomaly was diagnosed by cardiac catheterization and confirmed by multislice computed tomography.
