“…They may arise in other locations, such as the right atrium (RA) (18% of cases) [5], and, more rarely, in the aorta, pulmonary artery, ventricles, vena cava, or even other organs [3,6]. The differential diagnosis is performed mainly between rhabdomyoma or thrombus [2].…”

“…Although this tumor presents with benign histological features, the signs and symptoms caused by myxomas are atypical and highly variable and can result in a difficult diagnosis of this neoplasia [3,8]. According to the size, mobility, and location of the tumor as well as physical activity and body position, patients' symptoms may have an asymptomatic course or progress with thromboembolic events that may even lead to sudden death [3,4,9].…”

“…The classic triad found in patients with cardiac myxoma is characterized by obstruction of blood flow, constitutional symptoms, and thromboembolic events [3,4,7]. The obstruction of blood flow leads to intermittent heart failure, and, similar to systemic non-specific flu-like malaise symptoms, there is usually a low fever of long duration, arthralgia, anorexia, and thromboembolic events [7].…”

IntroductionPrimary intracardiac tumors are rare and approximately 50% are myxomas. The majority of myxomas are located in the left atrium and have variable clinical presentation. We report a case of a large myxoma in the right atrium, which is an uncommon location for this type of tumor.Case presentationA 45-year-old Caucasian woman with a history of palpitation had dyspnea on great exertion and discrete weight loss. A cardiac evaluation showed splitting of S1. An echocardiogram showed a large mass in the right atrium, suggesting myxoma; chest computed tomography confirmed the diagnostic hypothesis. Our patient underwent surgical treatment with excision of a 10 cm multilobulated mass. She presented with supraventricular tachycardia during the operation. She was placed in the intensive care unit and her condition improved after the use of amiodarone. The diagnosis of myxoma was confirmed by histopathological study.ConclusionsIn this case report, we emphasize the rarity of large myxomas in the right atrium and the difficulty of differential diagnosis given their dimension and location.

“…Myxomas are the most common heart tumors, accounting for about 50% of benign primary cardiac tumors, with the majority located in the left atrium (LA), and 80% originate in the interatrial septum. Clinically, they often present themselves with signs and symptoms of mitral valve disease or thromboembolic events [1,2]. This is a patient with multiple left atrial myxoma, in case it is not mentioned in the literature, will be reported below.…”

Primary cardiac tumors are infrequent, with an incidence between 0.001% and 0.2%, mostly comprising benign histological characteristics in 75% of these cases. Myxomas account for approximately 50% of these neoplasms. As regards location, 75-80% of myxomas are in the left atrium, 18% in the right atrium, and more rarely in the ventricles. We report a case of a patient in functional class (FC) IV New York Heart Association (NYHA) and postoperative histological diagnosis of multilobular myxoma originating in the posterior left atrial wall. Clinical evaluation 3 months after surgery suggested NYHA functional class I and echocardiographic absence of intracardiac masses.Descriptors: Myxoma. Heart neoplasms. Heart atria. ResumoOs tumores primários cardíacos são infrequentes, apresentando incidência entre 0,001% a 0,2%, com características histológicas benignas em 75% dos casos. Os mixomas correspondem a aproximadamente 50% dessas neoplasias. Quanto à localização, 75 a 80% dos mixomas estão no átrio esquerdo, 18% no átrio direito, e mais raramente nos ventrículos. Relatamos o caso de um paciente em classe funcional (CF) IV New York Heart Association (NYHA) e diagnóstico anatomopatológico pós-operatório de mixoma multilobular originário na parede posterior atrial esquerda. À avaliação clínica no 3º mês pós-operatório se encontrava em CF I NYHA e a ecocardiográfica com ausência de massas intracardíacas.Descritores: Mixoma. Neoplasias cardíacas. Átrios do coração.
