ABSTRACT
Primary tumors of the heart are rare, their estimated incidence ranging between 0.0017-0.19%, and among them cardiac myxomas are the most common (50%). Right atrial localization is uncommon, occurring only in 15-20% of cases. Their clinical presentation ranges from an asymptomatic status to the presence of constitutional symptoms or symptoms pointing to the presence of cardiac obstruction or pulmonary embolism. A case is presented of a 36-year-old male patient with a history of asthenia, palpitations and reduced functional capacity. Transthoracic echocardiography revealed a large mass in the right atrium which prolapsed into the right ventricle and obstructed the tricuspid valve. The patient underwent cardiopulmonary bypass surgery and the mass (9x9 cm) was removed without any complication. Histological examination confirmed the diagnosis of myxoma.
