[Coronary embolism revealing mitral valve stenosis].
We report a case of myocardial infarction with normal coronary arteriography in a 39-year-old woman presenting with tight mitral stenosis complicated by atrial extrasystoles and spontaneous atrial contrast at echocardiography. The diagnosis of coronary embolism was most probable. Coronary embolism is a rare disease, usually due to a blood clot or, less frequently, to a vegetation of endocarditis starting in a heart valve. The left network is usually involved, with typical myocardial necrosis. Coronary arteriography is sufficient to make the diagnosis. Preventive treatment is essential.
