Transthoracic echocardiography in 4-chamber views showed a classical dumbbell-shaped myxoma of 4.1 cm x 3.1 cm sized across the interatrial septum through the foramen ovale. Some specks of hyperechoic spots were marked possibly due to calcification

Transthoracic echocardiogram and transesophageal echocardiogram unanimously disclosed a classical butterfly wing (so-called dumbbell shaped) intracardiac myxoma with moderate tricuspid valve regurgitation due to direct impingement on tricuspid valve [Figure 1 and Video 1].
The excised tumor mass consisted of 4.1 cm x 3.1 cm mobile right and left atrial myxomas connected by a common stalk which passed through the atrial septum, collectively resembling the shape of a dumbbell (butterfly). Smooth and jelly-like surface with foci of hemorrhage was evident
