Objective. To describe and classify coronary and non-coronary cardiovascular findings using CT Angiography of coronary arteries in a group of patients treated at the University of Chile Clinical Hospital. Materials and Methods: We retrospectively reviewed 87 CT Angiograms of coronary arteries. The presence of coronary atheromatous disease and its severity was recorded and classified as non significant (<50%) or significant stenosis (>50%), subdividing this latter group into moderate (51-70%), severe (71-99%) or occlusion (100%). In each patient the number of affected arteries was recorded. The presence of coronary stents and bypass was analyzed, showing their location and permeability. Non-coronary cardiovascular findings were recorded. Results. A total of 51 patients had coronary atheromatous disease that was able to be classified using CT Angiography. Of these, 14 (27%) showed non significant stenosis and 37 (73%) significant stenosis. In the cases with significant stenosis 19 were moderate, 11 severe and 7 occlusion. The number of affected arteries was one in 43% of the patients, two in 39% and three in18%. Five patients had coronary stents, one of those occluded. Three patients had triple coronary bypass, each with at least one occluded graft. Fourteen patients showed non-coronary cardiovascular findings, the most common being aortic valve disease. Conclusion. The CT Angiogram of coronary arteries is a useful examination to classify atheromatous coronary disease and determine its severity. It is useful for evaluating coronary stents and bypass, and to determine their permeability. It also provides information relating to non-coronary diagnosis on cardiac, aortic and pericardial levels.
