[A case of cardiac myxoma associated with long-term lasting symptoms of mitral stenosis].

We reported a case of 70-year-old woman whose left atrial myxoma was resected. She had been suffered from low cardiac output due to mitral stenosis for 15 years or more. Resection of the myxoma corrected mitral stenosis completely. Cardiac output and pulmonary wedge pressure, however, were not improved following the operation. Postoperative echo- and angiocardiography revealed marked early closure of the mitral valve. These findings indicate that left ventricular compliance should be reduced if inflow stenosis continued for a long period and it is difficult to improve depressed ventricular function even if mitral stenosis is completely removed.
