Transthoracic echocardiogram revealed two intracardiac masses which attached to the atrial septum, with a larger one in the LA (69 mm x 39 mm) while a relatively small one in RA, both of these masses were prolapsing through the mitral/tricuspid valve during diastole (Figure 1).

During the operation, an incision was made in the right atrium exposing a 30 by 40 mm gelatinous mass, which was attached to the interatrial septum (Figure 2).
Microscopic features of the specimen: it composed of satellite myxoma cells, inflammatory cells, and much basophilic substance (200x).
