Objective: To determine the clinical value of 64-slice computed tomography angiography (CTA) in the diagnosis of coronary artery anomalies.
Methods: The coronary artery imaging data of 852 patients who underwent 64-slice CTA from July 2006 to May 2007 were retrieved. The imaging features of coronary artery anomalies confirmed by selective coronary angiography were reviewed.
Results: Eight (0.9%) coronary artery anomalies were found in the patients, which included 3 cases of anomalous aortic origin of coronary arteries, 3 cases of anomalous origin of the left main coronary artery from pulmonary artery, 1 case of coronary fistula from the right coronary artery to right atrium, and 1 case of coronary aneurysm.
Conclusion: The 64-slice CTA can detect coronary anomalies and delineate the anatomic relationships among the peripheral structures, which can be considered as an early screening for coronary anomalies.
