WATANABE, K., HIROKAWA, Y., OHTAKI, E., NAGAI, T., SHIBATA, A. and EGUCHI, S. Usefulness of Two-Dimensional Echocardiography for Diagnosis of the Sites of Origin in Myxoma. Tohoku J. exp. Med., 1983, 139 (3), 327-328-Three patients with atrial myxoma, two in the left atrium and one in the right were studied using two-dimensional echocardiography. An analysis by four cross sections, long and short axis, subcostal and four chamber views of the left ventricle showed that the stalk of one left atrial myxoma adhered to the anterior commissure, the other to the left atrial wall underlying on the aortic posterior wall, and that of right myxoma to the free wall of the right atrium. The myxomas were successfully removed by surgical intervention in all cases, where the sites of stalk were verified to be identical with those diagnosed by echocardiography.
