Bedside echocardiography in the four chamber view shows a free-floating atrial clot (arrow) as it glides between the right atrium (RA) and moves to the right ventricle (RV) during cardiac diastole and systole. A, the clot (arrow) is seen starting in the RA, B, moving through tricuspid valve (arrowheads seen in A), C, and finally seen in the RV.. LA, left atrium. LV, left ventricle
