FIG 4. Relative surface pressure maps (left images; in mm Hg) for both aneurysms and MPChA at different time moments of one cardiac cycle show marked pressure variations in the arterial aneurysm caused by the jet coming from the parent artery stenosis. High-pressure areas all over the cardiac cycle are seen opposite of the stenotic artery entry hole. Central and right images demonstrate the blood velocity (magnitude; in m/s) maps in two cross sections and outflow boundary.
