title: Spindle cell sarcoma of the mitral valve: an unusual cause of acute coronary syndrome in a child.
abstract: We present an unusual case of acute myocardial infarction by embolic obstruction of both the left anterior descending and right coronary arteries in a 14-year-old girl. Echocardiography showed mobile lesions on the mitral valve and into the left ventricular outflow tract with poor left ventricular function, eventually suggesting endocarditis. Successful surgery comprised mitral valve plasty after complete resection of the tumoral lesion, in association with coronary artery embolectomy. Histologic examination revealed a malignant spindle cell sarcoma treated with adjuvant chemotherapy. We emphasize here the differential diagnosis of acute coronary syndrome in children by a rare cardiac tumor.
