MessaoudiAbstractA 10-year-old child experienced syncope on exertion, preceded by chest pain and palpitations. The physical exam had no particularities except for a diastolic roll at the mitral area. The initial electrocardiogram showed a ventricular tachycardia successfully wiped out by cardioversion. The electrical control showed an extensive anterior myocardial infarction. Emergency Doppler echocardiography showed a dilated LV, akinesia of the apical and middle segments of the anterolateral wall and of the apex with a reduced LVEF of 35%. A mass covering almost all of the left atrium was noted evoking a myxoma. A thoracic angiography scan and a coronary-scan confirmed the diagnosis, showed anterior cardiac ischemia and normal coronary arteries. The final diagnosis was a left atrial myxoma complicated by a coronary artery embolism. The child underwent surgical resection. Histopathological examination confirmed the diagnosis.In this paper, a review of the literature concerning left atrial myxomas complicated with coronary embolisms in children showed the rarity but severity of such association, thus requiring a high degree of clinical awareness to obtain a timely diagnosis and to not delay the treatment.
