Preoperative transthoracic echocardiography: (a) end-diastolic frame, showing a giant
6.4 x 4.8 cm mobile mass (*) attached to the interatrial septum. The mass is prolapsing
and is about to incarcerate into the left ventricle (white arrow) and (b) end-systolic
frame, showing a giant mobile mass (*).
