Hemodynamic patterns of the abdominal aorta were assessed with streamlines and pathlines, and wall shear stress was analyzed on color coded cine maps postprocessing 4D Flow data. As a result, kinking aorta suffered vortex or turbulent flow at the inner curvature of the aorta mainly during the early-diastole and this resulted in significantly low wall shear stress of the corresponding portion, while non-kinking aorta did not. Kinks of the abdominal aorta create vorticity or turbulence of the blood flow at the inner curvature of the kinking aorta,@which may have further atherogenic effect of the corresponding aortic wall.
