title: [Myxoma of the right atrium].
abstract: The authors report the case of a 31 year-old male with right atrial myxoma whose clinical manifestations included: malaise, dizziness and dyspnea on great exertion. At physical examination, a tricuspid systolic and diastolic murmur of mean intensity was found. The chest radiography and the electrocardiogram signs were of right atrial and ventricular enlargement, and the diagnosis was made with the B-mode echocardiogram. The patient underwent surgical removal of the tumoral mass and diagnostic confirmation was made with the histopathologic study of the 75 x 50 x 40 mm piece. The patient obtained clinical, electrocardiographic and radiologic remission.
