Abstract
Myxoma is the most common primary tumor of the heart and can arise in any of the cardiac chambers. This paper reports A 50 -year-old woman without medical history and any cardiovascular risk factors was hospitalized for exertional dyspnea and palpitations from three months and signifiant weight loss. Transthoracic echocardiogram showed a giant left atrial myxoma mobile confined to the left atrium in systole, in diastole the tumor was seen prolapsing across the mitral valve into the left ventricle and partially obstructing it and causing severe functional mitral stenosis with a mean gradient of 21,3 mmHg. Severe pulmonary hypertension was confirmed by Doppler PAPs =137 mmHg. The patient was scheduled for cardiac surgery with good outcome.
Highlights
Myxoma is the most common primary tumor of the heart and can arise in any of the cardiac chambers, the left atrium is the most commonly involved (75%) [1,2]
The classic triad of myxoma clinical presentation is characterized by intracardiac obstruction, embolisms and constitutional symptoms with fever, weight loss, or symptoms resembling connective tissue disease [1,2,3]

Summary
Myxoma is the most common primary tumor of the heart and can arise in any of the cardiac chambers, the left atrium is the most commonly involved (75%) [1,2]. Case report A 50-year-old woman patient without medical history and any cardiovascular risk factors was hospitalized for exertional dyspnea and palpitations from three months and signifiant weight loss. She related worsening of symptoms in the last week before admission. In diastole (Figure 2) the tumor was seen prolapsing across the mitral valve into the left ventricle and partially obstructing it and causing severe functional mitral stenosis with a mean gradient of 21,3 mmHg. A mild mitral regurgitation was found. The clinical course was uncomplicated and the patient was discharged after three weeks with good outcome
