Origem anômala da artéria circunflexa e espasmo coronariano / Anomalous origin of the circumflex artery and coronary spasm

ABSTRACT

A 43 year-old female patient with angina pectoris and vasospasm demonstrated in the anomalous left circumflex (Cx) and right coronary (RCD) arteries by coronary angiograph. Origin of the left Cx from the RCD is the most common coronary anomaly and generally, is considered to be benign. Nevertheless, myocardial ischemia in patient with this anomaly has been described. To our knowledge, this is the first reported case of coronary vasospasm occurring simultaneously in the anomalous left Cx and RCD arteries. The diagnostic troubles and the potential danger of this association were emphasized.
