Detection of coronary artery anomalies and coronary aneurysms by multislice computed tomography coronary angiography.
We report some variants, anomalies and aneurysms of the coronary artery tree observed in patients referred to our radiology department for suspected or known coronary artery diseases. 265 patients, with heart rate < 70 beats per minute and stable clinical conditions, underwent 64-MSCT. They were intravenously given contrast medium followed by saline as a chaser. Images and data were reconstructed and evaluated by two radiologists. Seven out of these patients (5 males and two females) were found to have abnormalities (variants or anomalies) of coronary arteries or coronary aneurysms, with an incidence respectively of 1.88% and 0.75%. Two patients had an anomalous origin of the left coronary artery from the pulmonary artery, as previously described (Castorina S et al., 2008). As regards the other patients, one had separate origins of the anterior descendant and circumflex arteries from the left lateral sinus with two ostia, one had quadrifurcation of the left coronary trunk, one had agenesis of the left coronary ostium and trifurcation of the right coronary artery and two had coronary aneurysms. Images acquired by 64-MSCT, because of their spatial dislocation, permit anatomical study from different perspectives. Our data confirm the ability of MSCT to evaluate, in a few seconds, anomalies of coronary arteries offering additional information for a more complete diagnosis.
