Abstract

A 51-year-old woman was admitted to the hospital for close exploration and treatment of palpitation and disagreeable sensation on the chest. Before this admission, she visited another hospital because of chest pain and was found having a tumor in the left ventricle on an echocardiography; thereafter her palpitation and chest disagreeable sensation persisted. Cardiac catheter revealed no lesions in the coronary arteries. Cardiac CT scan visualized no tumor, but an echocardiography showed a left ventricular tumor about 10mm in diameter. At surgery, the left ventricle was longitudinally incised under extracorporeal circulation, and then an edematous tumor 8mm in size localized in the ventricular septum was excised together with cardiac muscle adhesive to the tumor. Histopathologically it was myxoma. The postoperative course was uneventful without any complications. The patient was discharged from the hospital.<br> Left ventricular myxomas are extremely rare compared with left atrial myxomas. Besides, those with the diameter of less than 10mm present difficulty in identification on CT, because hard blood flow in the left ventricle causes disarranged flow of a contrast material; and IL-6, CRP, and eryhrocyte sedimentation rate in those patients sometimes are in normal ranges.<br> Consequently echocardiography might be most advantageous in diagnosing left ventricular myxoma.
