    Abstract:
    BACKGROUND: Primary cardiac tumors are rare, and approximately 90% of them are benign. Myxoma is the most common type of these tumors occurring in the left atrium in 75-85% of cases. The tumor can cause the left atrio-ventricular valve obstruction and embolization phenomenon. Case presentation We reported a case of 54-year-old man with complaints of dyspenea and amnesia. In our patient, transthoracic echocardiography revealed a mass of 28*63 mm attached to the upper intra-atrial septum, which was prolapsing through the mitral valve into the left ventricle during diastole, being indicative of the left atrial myxoma. On examination, he was alert and conversant, and no pathological abnormality was observed in the examination of cardiovascular, gastrointestinal, respiratory, hepatic, renal and nervous systems. After myxoma diagnosis, the tumor was removed under cardiac surgery and discharged under good conditions. In the telephone follow-up after discharge, the patient recovered and did not report the disease and surgery complications. CONCLUSIONS: Patients with cardiac myxoma are usually asymptomatic, but they may have manifestations related to the embolism phenomenon or intracardiac obstruction. Therefore, myxoma may represent an emergency. Surgery should be performed as soon as possible. If surgery is delayed, the patient may suffer from serious and irreversible complications, such as stroke and cardiac arrest.
