Figure 1 a. Orientation of planes for blood flow and wall sheer stress quantification. Fig 1b. 3D flow visualization of a 21 year-old healthy volunteer demonstrating non-helical flow at the aortic annulus, sinuses of Valsalva and sinotubular junction with helical flow in the distal ascending aorta, arch and proximal descending aorta. Fig 1c. 51 year-old male with Loeys-Dietz syndrome due to a novel mutation in the TGF β Receptor gene, with prior aortic valve and root replacement surgery, following Type A aortic dissection showing complex disturbance of flow with complex vortices and helices. Two distinct lumens are seen in the aortic arch, which reunite in the proximal descending aorta to form a pronounced right-handed helical flow jet.
