Multifocal right atrial myxoma and pulmonary embolism.

Abstract

Multifocal cardiac myxoma with greater than two foci is rarely reported in the literature. We report a case of a 22-year-old woman who presented with profound right heart failure, and was found to have seven right atrial myxomas with bilateral pulmonary embolism, including near-complete occlusion of right pulmonary arterial flow. Multifocal atrial myxoma occurs most often in the familial setting, and often is associated with recurrence. Her disease was nonfamilial. She was successfully treated with surgical resection, and has had complete recovery with no evidence of recurrence over a 4-year period.
