[A case of left atrial myxoma in the elderly (77-year-old)].

We reported a case of a 77-year-old female, whose left atrial myxoma with a cyst, which had been identified by 2D echocardiography, was successfully resected. Apart from echocardiogram-revealed tumor hemorrhages in atrial myxomas, reports of echo-lucency within cardiac tumors are considerably rare. She was successfully operated on, and the section through the tumor specimen showed a cyst with a diameter of 10 mm, that corresponded to the echo-lucencies noted on the 2D echocardiogram. Even in an elderly patient, surgical treatment of left atrial myxoma offers excellent results with low morbidity and low mortality.
