Recurrent cardiac myxoma: seeding or multifocal disease?

We describe a patient with left atrial myxoma followed by a second lesion in the left ventricle. Previous reports of “recurrent” myxoma were studied, with the following conclusions: There is little evidence for the process of myxoma seeding, local recurrence can occur through inadequate resection or malignant change, and many alleged recurrences are at a different site and multifocal disease occurs frequently in the familial setting.
