Multi-row Detector Computed Tomography Coronary Angiogram Image of an Anomalous Left Coronary Artery from the Pulmonary Artery

Multi-row detector computed tomography (MDCT) is considered as effective tool for diagnosing coronary artery anomalies1. We describe a case of an anomalous left coronary artery from the pulmonary artery (ALCAPA) in which MDCT coronary angiography was conclusive for an accurate diagnosis. After riding a bicycle up a long hill, a 13-year-old boy had an attack of syncope lasting several minutes, and he was brought to a nearby medical center by ambulance. He showed no neurological symptoms there, and his head computed tomography appeared normal. However, electrocardiography showed atrial fibrillation, and he was immediately transferred to our center for further examination and treatment. The heart rhythm returned to sinus rhythm during the transfer. Vital signs on arrival were: heart rate, 76/minute; respiratory rate, 40/minute; and blood pressure, 110/53 mmHg. The consciousness level was clear, and no abnormalities were found on physical examination.
