Figure legends:
Figure 1. Electrocardiogram (A) 9 days before admission, and (B) at emergency department with tachycardia, biatrial enlargement (blue arrows indicate right atrial enlargement, red arrows indicate left atrial enlargement).
Figure 2. Computed tomography angiogram of (A) axial and (B) coronal slices shows saddle embolism (red arrowheads). aAo = ascending aorta, cAo = aortic arch, dAo = descending aorta, LPA = left pulmonary artery, MPA = main pulmonary artery, RPA = right pulmonary artery, SVC = superior vena cava.
Figure 3. Echocardiography of (A) apical 4-chamber view with a sausage-like thrombus (red arrowheads) in the right atrium straddle the patent foramen ovale (green arrowhead) which was consistent with thrombus-in-transit, and (B) color Doppler showing tricuspid regurgitation jet (orange arrows) hitting the thrombus (red arrows). LA = left atrium, LV = left ventricle, RA = right atrium, RV = right ventricle.
Video 1. Echocardiography of apical 4-chamber view showed the right ventricular dilatation and hypokinesia with classic McConnel’s sign. There was a sausage-like thrombus (red arrowheads) in the right atrium straddle the patent foramen ovale (green arrowhead) which was consistent with thrombus-in-transit. LA = left atrium, LV = left ventricle, RA = right atrium, RV = right ventricle.
Video 2. Echocardiography with color Doppler zooming up the right atrium. There was tricuspid regurgitation jet (orange arrows) directing toward the thrombus (red arrowheads) straddle the patent foramen ovale (green arrowhead). RA = right atrium, RV = right ventricle.
