“…Many of these findings are influenced by changing positions. Right atrial myxomas have been found to be associated with abdominal distension due to ascites [ 2 , 4 ]. Another study evaluating atrial myxomas found a neurological symptom rate of 16.9% with cerebral infarction being the most common complication among neurological conditions [ 6 ].…”

Atrial myxomas are the most common form of primary benign cardiac tumors. The left atrium is typically the most common location while right atrial myxomas are much rarer and only occur in about 15%-25% of all myxoma patients. Typically, left atrial myxomas have the ability to cause symptoms such as syncope. We report a case of a 67-year-old female who presented with complaints of palpitations, dizziness, and near-syncope that had been ongoing for about a year. Other causes of syncope were investigated and ruled out. A transthoracic echocardiogram (TTE) found a large 4.3 x 4.0 cm spherical mass in the right atrium which was confirmed by surgical resection and immunohistochemistry to be a myxoma. The patient's condition of syncope-like symptoms warrants elevating atrial myxomas to a higher position in the diagnostic differential.

“…Roughly 75% of cardiac tumors are benign. Approximately 50% of these benign tumors are myxomas [1][2][3][4][5]. Characteristic findings of atrial myxomas include syncope, dizziness, orthopnea, pulmonary edema, cough, palpitations, fatigue, hemoptysis, and chest pain.…”

“…МС имеет разнообразные клинические проявления, обусловленные нарушением проводимости, обструкцией и дисфункцией клапанного аппарата, но большая часть миксом протекает бессимптомно [9]. Зачастую миксома является диагностической находкой при обследовании, операции на сердце или при аутопсии.…”

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.

Background Cardiac syncope can result from an atrial myxoma due to outflow obstruction. Myxoma is the most common primary cardiac tumor that may cause sudden death and the nonspecific symptoms may make early diagnosis difficult. Case presentation A 27-year-old man presented to our emergency department after two episodes of syncope and severe fatigue. He had no complaint of fever, weight loss, sweating, chest pain or dyspnea. Vital signs were within normal limits. A loud heart S1 was detected and normal neck veins. Other systemic examinations including neurological assessment were normal. Electrocardiography showed normal sinus rhythm. An obvious variability in heart rate was noticed on cardiac monitor changing by the patient’s position. Point-of-care ultrasonography (PoCUS) showed a large hyperechoic lesion with a well-defined stalk originating from the left atrium (LA). Thus, the patient was transferred to a cardiac surgery center for surgical intervention. Histopathology reported an LA mass compatible with myxoma. Conclusions Emergency physicians should be familiar with the vague presentations of cardiac tumors to improve patient outcomes. It is beneficial to take advantage of bedside ultrasound for prompt diagnosis and subsequent treatment.
