Figure 6. Modulation of stroke propensity for two aortic arch models under the (A) normal and (B) AF flow condition at the high ejection speed.

Overall stroke propensity for the clots of 2–6 mm diameter with a range of clot ejection speeds of 0–0.7 m/s released at three different ejection points indicated in Fig. 1B under the (C) normal and (D) AF flow conditions. Case I and II indicate upper and lower ranges of carotid diameters observed in the previous study (23), respectively. Also, they represent two different branch sizes and locations relative to aorta.
