Primary heart tumors are an extremely rare disease, with a prevalence of 0.0017%0.03% in the population according to various data.
 Heart benign most cases, and more than half such formations represented by cardiac myxomas. Myxoma is common primary tumor; however, its number small among general population. that affects valves pathology. For first time, variance changes was described 1934. Most often, myxomas localized at atrial septum level near oval fossa. One typical signs myxoma narrow leg uneven surface, which causes risk embolism. Echocardiographic examination magnetic resonance imaging currently methods choice when suspecting presence volumetric formation. With atypical tumor localization, conducting mandatory differential diagnosis valve vegetations papillary fibroelastoma necessary.
 Herein, presented elderly patient complaints shortness breath, stabbing pains left chest, arrhythmias history aspiration pneumonia esophageal extirpation stomach esophagogastroplasty. During examination, revealed paroxysmal form fibrillation (outside paroxysm), chronic failure, arterial hypertension. The clinical data were not characteristic enough for possibility infectious endocarditis valvular vegetations. echocardiographic multispiral computed tomography bolus contrast enhancement on surface posterior flap mitral additional volume formation 59 mm size, rounded shape, clear contours, together into ventricular cavity systole. optimally visualized using Fiesta-CINE mode modified two- four-chamber projections. removed suture plasty artificial blood circulation conditions. histological morphological myxoma. postoperative period proceeded without complications.
