..., incompressible and axisymmetric non-Newtonian blood flow through an artery with stenosis under the influence of magnetic field was considered. Both moderate and severe stenoses are taken under consideration to offer better understanding of the practical problem of blood flow through stenosed artery...

...Ishan Goswami; Srikara V. Peelukhana; Marwan F. Al-Rjoub; Lloyd H. Back; Rupak K. Banerjee The variation in FFR with the diameter under non-MI conditions is shown in Fig. 5( a ) . FFR values for mild stenosis for N1 and N2 were within 5% difference (Table 3 ). A similar trend was observed...

... 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...

...Leonie Rouleau; Joanna Rossi; Richard L. Leask Inflammation plays a key role in the development and stability of coronary plaques. Endothelial cells alter their expression in response to wall shear stress (WSS). Straight/tubular and asymmetric stenosis models were designed to study the localized...

...Dalin Tang; Chun Yang; Shunichi Kobayashi; David N. Ku Severe stenosis may cause critical flow and wall mechanical conditions related to artery fatigue, artery compression, and plaque rupture, which leads directly to heart attack and stroke. The exact mechanism involved is not well understood...
