(a) Transthoracic echocardiogram apical four-chamber view in diastole showing a large thrombus (asterisk) extending from the right atrium to the left atrium via a patent foramen ovale (arrow). (b) Apical four-chamber view in diastole demonstrating prolapse of the thrombus across the mitral and tricuspid valves.

His transthoracic echocardiogram demonstrated a large highly mobile elongated mass consistent with thrombus (asterisk Figure 1(a)) in the right atrium which crosses the interatrial septum, presumably through a patent foramen ovale (arrow Figure 1(a)) into the left atrium. The thrombus also prolapses across both the tricuspid and mitral valves during diastole (Figure 1(b)) and measures greater than 10 cm in length.
