Noninvasive Imaging of Anomalous Origin of the Left Coronary Artery From the Pulmonary Artery
Electron beam computerized tomography (EBCT) during intravenous administration of contrast medium showed an anomalous origin of the left coronary artery from the pulmonary artery, sometimes known as the Bland-White-Garland syndrome. This 28-year-old woman presented with chest pain caused by progressive myocardial ischemia. In this case, a right coronary arteriogram confirmed an enlarged right coronary artery, and both the left anterior descending branch and the circumflex artery were supplied by collateral circulation. The left main artery was connected with the pulmonary trunk during the late phase of the right coronary arteriogram. These axial EBCT images (Figure⇓) were performed with 3-mm thickness and 100-ms acquisition time. Cardiac motionless images allow clear visualization of both the anomalous origin of the left main coronary trunk and enlarged right coronary artery. We can see that the left main trunk supplied the left anterior descending branch and circumflex artery.
