A Rare Case Report on Left Atrial Myxoma

Abstract

Left atrial myxoma is the most common benign primary cardiac tumor, typically arising from the interatrial septum. It is associated with nonspecific systemic, embolic, and obstructive symptoms, making early diagnosis and timely intervention essential. Early surgical excision is the treatment of choice once the diagnosis is established. We report the case of a 60-year-old female with known risk factors for coronary artery disease, including diabetes mellitus and hypertension, who presented with fever, progressive dyspnea for 8–10 days, and a transient episode of right-sided weakness lasting 5–10 minutes. Transthoracic echocardiography revealed a mobile left atrial mass attached to the interatrial septum, suggestive of myxoma. Preoperative coronary angiography showed significant coronary artery disease. The patient underwent successful surgical excision of the left atrial myxoma along with concomitant coronary artery bypass grafting under cardiopulmonary bypass. Histopathological examination confirmed the diagnosis. The postoperative course was uneventful, with complete resolution of symptoms and no recurrence on follow-up.
