Anomalous origin of the left coronary artery from the right sinus of Valsalva in a 62-year-old woman with unstable angina pectoris: a case report

Abstract

Anomalous origin of the left coronary artery from the right sinus of Valsalva is a rare congenital coronary anomaly. We report a case of a 62-year-old woman with a history of hypertension, diabetes type 2 and hypercholesterolemia who was admitted to the local hospital because of unstable angina pectoris. Coronary angiography was performed revealing the anomalous left main coronary artery arising from a single ostium in the right sinus of Valsalva together with the right coronary artery which showed a 90% proximal stenosis. The patient was referred to our hospital for further management. Multislice computed tomography (MSCT) coronary angiography confirmed these findings and determined coursing of the anomalous left coronary artery anterior to the pulmonary trunk. The proximal RCA lesion was successfully treated with direct stenting. She is asymptomatic on clinical follow-up at 18 months.
