A Case of Anomalous Left Coronary Artery Originating from the Right Sinus of the Valsalva Presenting with Syncope / 대한내과학회지

ABSTRACT

Congenital anomalies of the coronary artery are associated with various symptoms including syncope, myocardial ischemia, and sudden cardiac death. The abnormality depends on the adjacent structure and pathway of the coronary artery. Most patients with an anomalous left coronary artery that arises from a right coronary sinus of the valsalva have no symptoms and are usually diagnosed at autopsy. Therefore, their first symptom might present as sudden death, particularly when the left coronary arterial course is between the aorta and the pulmonary trunk. Symptomatic patients could be diagnosed early with an anomalous coronary artery, and the risk of fatal events could be decreased by surgical correction. Here, we report the case of 62-year-old male who experienced a first episode of syncope with an anomalous left coronary artery arising from the right sinus of the valsalva with a separate orifice from the right coronary artery. He is alive and in good health receiving medical treatment, and has had no medical events for over 2 years.
