A. Schematic providing orientation of ultrasound snapshot still frames to assist for examining still frames in (B). Components of the aortic arch: AA-ascending aorta, DA-descending aorta, BC-brachiocephalic artery. CC-common carotid artery. Plaque indicated by arrow forms at the bifurcation of the BC and AA. A ruptured plaque is seen flapping in the BC lumen as indicated by dashed line on the inferior wall of the BC.

B. Still frame snapshots of a cine loop of ultrasound images. Cine loop was 300 images per second with chosen still frames at 2.967 sec/3.174 sec/4.278 sec taken from a 20 second cine loop provided as an on-line video supplement. Components of the aortic arch: AA-ascending aorta, DA-descending aorta, BC-brachiocephalic artery. CC-common carotid artery. Yellow arrow points to plaque formation on superior wall of BC at the bifurcation of the BC with the AA. Red arrow highlights cap flap moving in the plaque lumen during the cardiac cycle with the three chosen still frames showing from left to right a flap which is not obstructing the lumen/half obstructing the lumen/occluding the BC lumen.
