Left Atrial Mass in a Patient With Rheumatic Mitral Stenosis: A Case Report

Rheumatic mitral stenosis is common in developing countries. The left atrium, due to its large size, is prone to thrombus formation, and the presence of a large mass is more suggestive of a clot. Myxomas are some of the most common benign heart tumors; however, they have been reported rarely in rheumatic mitral stenosis. Here, we describe a patient with mitral stenosis who presented with a large left atrial mass, which was ultimately diagnosed as a tumor. (Iranian Heart Journal 2021; 22(1): 106-108)
