[Case report and review of a voluminous right atrial myxoma revealed by heart failure].

Right atrial myxoma is a rare disease and its clinical presentation is not specific. The usual mode of revelation is heart failure. The most frequent complications are pulmonary embolism and atrioventricular valve obstruction by the tumor. A 49-year-old woman was admitted to intensive care unit for heart failure. The echocardiogram showed a voluminous right atrial myxoma, appending to the interatrial septum. Its surgical excision under extracorporeal circulation was successfully performed. Histology confirmed the final diagnosis of myxoma. No complication was observed at 6 months follow-up. Copyright (c) 2009 Elsevier Masson SAS. All rights reserved.
