Patient-specific computational fluid dynamics—assessment of aortic hemodynamics in a spectrum of aortic valve pathologies

Using MR scans and computational fluid dynamics, the authors sought to evaluate differences in flow, shear stress, and oscillatory shear stress in normal individuals and patients with 1 of 4 different categories of aortic valvular disease.  The flow patterns were patient and category specific, and may provide the ability to determine interventions on an individualized basis.
