[Pattern of acute myocardial infarct in a patient with left atrial myxoma]

A case report on acute myocardial infarction in a patient without coronary risk factors, with left atrial myxoma. The diagnosis of an atrial tumor was made by 2-D echocardiography, which also provided important information about the size and mobility of the tumor and its point of attachment on the atrial wall. Coronary arteriography showed normal coronary arteries. This report considers the etiologic-pathogenetic mechanisms of acute myocardial infarction with normal coronary arteries. It presumes that, in this case, the acute coronary occlusion was due to the embolus from the atrial myxoma.
