Bottom Line: 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.The patient was scheduled for cardiac surgery with good outcome.

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.

Figure 2: Transthoracic echocardiography 4 cavity view shows a giant left atrial myxoma fills almost the entire left ventricular at diastole.

Mentions: Transthoracic echocardiography performed in emergency showed a giant left atrial mobile mass (72× 53 mm) attached to the interatrial septum and confined to the left atrium in systole (Figure 1). 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 also found. Severe pulmonary hypertension was confirmed by Doppler PAPs =137 mmHg. The patient was scheduled for cardiac surgery. During the operation, the tumor was excised through a sternotomy from a transseptal approach with a small portion of the atrial wall and the histopathological analysis found atrial myxoma. The clinical course was uncomplicated and the patient was discharged after three weeks with good outcome.
