Multiple Local Recurrent Myxoma.

Cardiac myxomas, usually considered benign tumors, occasionally pursue an aggressive clinical course. The recurrence of sporadic myxomas is much less frequent than that of complex or familial myxomas (1-3% vs. 22% vs. 12%, respectively). We report a case of sporadic myxoma with multiple local recurrence in the left atrium diagnosed by transesophageal two-dimensional echocardiography 4 years after the first excision.
