“…If the stalk of the tumor is not visible, CT and MRI examinations can help to exclude myocardial infiltration that is found in the malignant process. [5][6][7][8] In this case, an echocardiographic test was performed and found a mass in the left atrium attached to the intra atrial septum with 4.97 x 2.83 cm in size. The conclusion is mass in the left atrium suspected of myxoma.…”

Background: Primary tumors of the heart are scarce. Cardiac myxoma is a primary benign heart tumor most often found with an incidence of 0.5-1.0 cases per million population per year and 90% diagnosed in the fourth to seventh decades of life, rarely found in children. Cardiac myxoma is three times more common in women than in men. These tumors are mostly found in the left atrium.Case description: Female, a 49-year-old patient, came with palpitations, shortness of breath, and weakness since the previous six months. On echocardiography, found a mass in the left atrium suspected of a left atrial myxoma. Surgery was performed, and the specimen was sent for histopathological examination. Macroscopically, the tumor mass shows an irregular shape, brownish color, and spongy consistency. Microscopic examination shows the tumor consisting of proliferation of spindle-shaped and stellate cells, with oval to round nuclei, eosinophilic cytoplasm, mostly scattered, some of which are arranged cord and nest, infiltrative between the myxoid stroma and partially surround small blood vessels to form a vasoformative ring. The specimen also contains the proliferation of blood vessels, extravasation of erythrocytes, and the distribution of inflammatory cells and hemosiderophages. The result of the immunohistochemical examination with calretinin was positive.Conclusion: This case was concluded as cardiac myxoma based on clinical features, echocardiography, macroscopic, routine histopathological, and immunohistochemical examinations.

Cardiac atrial myxoma is a primary cardiac tumor with a prevalence of 0.0017-0.19% at autopsy. Anomalous origin of right coronary artery (ARCA) from opposite sinus of Valsalva is considered the second most common cause of sudden cardiac death among young athletes with an incidence of 0.09%-0.92% and mortality risk of 0-57%. We present a case of symptomatic left atrial myxoma in the presence of ARCA from the opposite sinus of valsalva. The myxoma was excised and the anomalous right coronary artery was re-implanted during the same operative session.

“…Опухоли различаются по размеру, в диапазоне от 1 до 15 см в диаметре, и весят от 15 до 180 грамм [2]. Клиническая картина МС напрямую зависит от размера новообразования, его локализации и степени обтурации атриовентрикулярных отверстий.…”

Right atrial myxoma is one of the rare diseases in cardiology practice. It is accompanied by an unclear clinical picture, and in most cases is asymptomatic and is an incidental finding. The article is devoted to the clinical observation of primary cardiac tumor and the difficulties of its differential diagnosis.Patient T, 58 years old, was hospitalized in a respiratory medicine center with complaints of cough with viscous sputum, weakness, fatigue, loss of appetite, shortness of breath on exertion, weight loss and sweating at night. The preliminary diagnosis was an exacerbation of chronic bronchitis. Then a space-occupying mass in the right atrium was revealed. Computed tomography imaging identified a bilateral pulmonary embolism. In the cardiac surgery department, surgical removal of the right atrial myxoma was performed.The diagnosis of right atrial myxoma was established by echocardiography, confirmed macroscopically during surgery, and then by histological verification.
