RESUMO
Coronary ectasia is a little common angiographic finding. Its prevalence varies between 0.3-5.3 por ciento in different series, although a recent study reports until 6.7 por ciento. Coronary ectasia is suffered mainly by males, and may be produced by different causes; however in most of the patients it seems to be related to coronary atherosclerosis. In fact, some authors consider it like a variant of the atherosclerotic disease of coronary arteries. We report the case of a 54-year-old white male who was admitted on intensive care unit because of ustable angina with electrocardiographic changes. Coronary angiography revealed severe coronary ectasia, mainly of the left main coronary artery and the proximal portion of left anterior descending artery. The greatest ectasia of the left main coronary artery that we have found in reviewed literature had 15.0 millimeters and ours sized 12.9 millimeters. Angiographic images are shown(AU)
