Key result
Surgical excision identifies a rare left atrial appendage myxoma initially mimicking thrombus in AF.
Why the study?
Distinguishing between a mass, thrombus, and tumor in the left atrium or left atrial appendage is very difficult with echocardiography, especially in patients with mitral valve disease and chronic atrial fibrillation.

LAA masses mimicking thrombus in mitral stenosis with AF warrant histopathology; this case extends the differential and leaves open true prevalence.
Myxoma is the most common benign tumor of the heart, but it is very rare for it to originate from the left atrial appendage. Distinguishing between a mass, a thrombus, and a tumor in the body of the left atrium with preoperative transthoracic or transesophageal echocardiography is very difficult, even more so in patients with mitral valve disease and chronic atrial fibrillation. A 50-year-old male patient was admitted for surgery with the diagnosis of mitral stenosis and chronic atrial fibrillation. Transesophageal echocardiography demonstrated a mass attached to the wall of the left atrial appendage. Histopathological examination of the mass showed an image compatible with a myxoma. We hereby describe a case of a left atrial appendage myxoma mimicking a left atrial appendage thrombus.

Sahratov et al. (2016) conducted a case report in Left atrial appendage mass, mitral stenosis, and chronic atrial fibrillation (n=1). Surgical excision and mitral valve replacement was evaluated on Histopathological diagnosis of the left atrial appendage mass. Surgical excision and histopathological examination of a left atrial appendage mass mimicking a thrombus in a patient with mitral stenosis and atrial fibrillation revealed a rare myxoma.
