title: Anomalous origin and interarterial course of right coronary artery associated with angina and proven ischemia.
abstract: Clinical significance of coronary arteries with anomalous origin and/or course is highly heterogeneous. Anomalies with the origin from the opposite sinus and interarterial course can be associated with angina, syncope, and sudden cardiac death. However, there are no clear guidelines for diagnosis and treatment of such cases. We present the case of a young lady who presented with typical angina, and later proved to have an anomalous right coronary artery (RCA) originating from the left sinus of Valsalva coursing between the aorta and pulmonary artery. This was associated with demonstrable stress ischemia with nuclear perfusion scan. The patient underwent surgery with a bypass graft to the anomalous RCA with complete relief of her angina.
