... by decreasing artery size, assuming non-Newtonian fluid, and increasing magnetic field strength. In the computations, the shear thinning behavior of blood is accounted for by the Carreau–Yasuda model. Computational results are compared and found to be inline with available experimental data. stenosis non...

... observed for N1 when compared to N2. Momentum components (units: mmHgml −2 min 2 ) were comparable for mild (N1: 0.0003 versus N2: 0.0002), and intermediate (N1: 0.0014 versus N2: 0.0010) stenosis cases. However, in the case of severe stenosis the coefficient increased from N2 (0.0029) to N1 (0.0134...

... contribute to an improved clinical understanding of MAC-related mitral stenosis. Moreover, they provide the ability to statistically evaluate between measurement locations, flow rates, and valve geometries for Doppler-derived pressure gradients. Determining these end points will contribute to greater...

... of blood vessels and that of abrupt rupture or hemorrhage of atherosclerotic plaque. Such rupture can be catastrophic and is difficult to predict. Currently, clinical assessments of plaque vulnerability are based largely on the percent stenosis, or how much the plaque narrows the arterial lumen diameter...
