Anomalous origin of the circumflex coronary artery from the right sinus of valsalva as a cause of ischemia at old age

Abstract

The case of a patient with an anomalous origin of the circumflex coronary artery causing myocardial ischemia and infarction is presented. Even though the anomalous artery was not located between aorta and pulmonary artery, this anomaly, which is usually considered benign, was responsible for the ischemic symptoms. Transesophageal echocardiographic study demonstrated an acute angulation at the proximal portion of this abnormal vessel, very close to its origin from the right coronary sinus, which we believe caused the abnormality in coronary flow in this patient.
