Primary tumor of the heart is comparatively rare. Recently, as the results of development of the cardiac catheterization, cardiovascular angiography and artificial heart-lung, both pre-operative diagnosis and successful extirpation of the tumor seem to be made more frequently. The case reported by SAKAKIBARA (1960) seems to be first one which operation succeeded in Japan. Concerning the nature of myxoma there are two theories, one is neoplastic, and the other non-neoplastic. And the latter has considered it to be a organized thrombus. With the diagnosis of mitral stenosis, operation was performed on a 28 years female to find a walnut-sized myxoma in the atrium. Because the artificial heart was not ready for use, the operation was terminated as exploratory one.
