title: [Myocardial infarction and coronary artery aneurysm].
abstract: Two cases of aneurysm of the right coronary artery are reported. These atheromatous aneurysms not associated with tight coronary stenosis were responsible for myocardial infarctions treated by early intravenous thrombolysis with a resultant limited area of necrosis. According to the literature, coronary aneurysms associated with stenosis are not rare. Aneurysms not associated with significant stenosis appear to be much less common and the prognosis of patients with such lesions would not seem to be worse than that of those with neither aneurysm nor significant coronary stenosis. From a pathophysiological standpoint, the development of local thrombosis appears to play a determinant role in terms of the clinical manifestation of these aneurysms and its prevention justifies the long term combined prescription of platelet antiaggregants and oral anticoagulants.
