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% us. 12%, respectively). We report a case of sporadic myxoma with m
ultiple local recurrence in the left atrium diagnosed by transesophage
al two-dimensional echocardiography 4 years after the first excision.
