Coronary ectasis: another form of atherosclerosis

Abstract:

In a review of 3,693 coronary angiographies carried out in our department for suspected coronary artery disease we evaluated the 69 patients (1.86%) in whom lesions of coronary ectasia were found. Most of them (n = 51) had associated stenotic lesions and only 18 patients had isolated ectasia. The most common localization of the 96 ectasia lesions found in these patients was the right coronary artery, followed by the left anterior descending and, finally, the circumflex coronary artery. The ectasia lesions were classified according to the morphological classification proposed by Ducceschi in the following types: I) fusiform; II) saccular; III) spherical; IV) linear or diffuse, and V) mixed. Most lesions in our series were diffuse. Regarding clinical features, significant differences were found in the higher incidence of atypical angina presentation in those patients with isolated ectasia lesions.
