(A) Transthoracic echocardiography, apical 4-chamber view. Cardiac mass in left atrium is attached to the interatrial septum in the region of the fossa ovalis (arrow). Histopathological characterization confirmed cardiac myxoma. (B) Abundant myxoid stroma with clusters of myxoma cells forming cords and ring structures (HE 100×).
