“…Primary cardiac tumors are rare, with an overall incidence of 0.056%‐0.02% of autopsy series 4 . Cardiac myxomas represent the most common benign cardiac tumor 5 . Other tumors include rhabdomyomas, fibromas, papillary fibroelastomas, hemangiomas, lipomas, hamartomas, teratomas, mesotheliomas, and paragangliomas.…”

“…Other tumors include rhabdomyomas, fibromas, papillary fibroelastomas, hemangiomas, lipomas, hamartomas, teratomas, mesotheliomas, and paragangliomas. Moreover, various types of sarcomas can be found, such as angiosarcoma (which most often originates in the right atrium), myxosarcoma, liposarcoma, fibrosarcoma, leiomyosarcoma, osteosarcoma, synovial sarcoma, rhabdomyosarcoma, undifferentiated sarcoma, reticulum cell sarcoma, neurofibrosarcoma, and malignant fibrous histiocytoma 4,5 …”

A cardiac myxoma is an authentic tumor that develops within the heart. Despite the typically benign histological characteristics, a cardiac myxoma may, on occasion, exhibit behavior reminiscent of malignant tumors. Most of these myxomas localize in the left atrium, often originating from a stalk near the foramen ovale region. The conventional presentation of cardiac myxomas includes a combination of obstruction, clot formation, and systemic symptoms, mirroring various other prevalent systemic diseases. They may manifest either spontaneously or through hereditary transmission. While familial myxomas are commonly linked to discernible genetic mutations, the precise molecular mechanisms underlying spontaneous myxomas remain somewhat enigmatic. Many individuals with myxomas may remain asymptomatic. However, should symptoms manifest, they can prove nonspecific and pose challenges in interpretation, particularly in instances of spontaneous heart myxomas. This report describes a 58-year-old female patient who presented with increasing severity of exertional dyspnea over a six-month duration. Initial differential diagnoses included common pulmonary and cardiac conditions, with a primary focus on chronic obstructive pulmonary disease and congestive heart failure. An echocardiogram revealed a large mass in the left atrium suggestive of a cardiac myxoma. Surgical resection confirmed the diagnosis. This case underscores the significance of including cardiac myxoma in differential diagnoses for progressive exertional dyspnea. Early detection and surgical intervention are crucial in mitigating potential complications like stroke, heart failure, or sudden cardiac death.

The clinical features of cardiac myxoma vary significantly from asymptomatic to severe cardiovascular complications like atrioventricular valve obstruction and thromboembolism depending on the location, size, and mobility of the tumor. Echocardiography is the diagnostic study of choice, and surgical resection is the method of choice to prevent complications. We report a case of a 47-year-old female who presented with exertional dyspnea, malaise, and weight loss. Physical examination was significant for jugular venous distension, basal crackles in lungs, 2+ pedal edema, and rumbling diastolic murmur at apex. CT of the chest revealed a hypodense filling defect in the left atrium. Transthoracic echocardiogram showed a 5.5 × 4.5 cm mobile density, likely myxoma, attached to the interatrial septum and prolapsing into the left ventricle during the diastolic phase, causing functional mitral stenosis. She underwent a resection of cardiac myxoma. The histopathology report confirmed the diagnosis of myxoma, and post-operative recovery was uneventful.
