Dynamic response of stenotic blood flow in vivo

Numerical Simulation of Blood Flow in a Stenotic Artery

The purpose of this paper is to develop a numerical computational methodology for the simulation of blood flow in a stenotic artery. As a first approach biochemical and mechanical interactions between blood and vascular tissue are neglected and the flow is considered through a rigid tube. Considering a non-Newtonian model numerical results are obtained for velocity and shear stresses distributi...

Evaluation of diastolic blood flow dynamic of the left ventricle in dogs with mitral valve regurgitation using vector flow mapping

Mitral valve regurgitation (MVR) is a common valvular disease in dogs. Hydrokinetic evaluation of the blood flow within the ventricles has become possible by vector flow mapping (VFM), which shows the blood flow within the ventricles in vector and vortex flows. Blood flow within the left ventricle of MVR dogs was compared at different stages of MVR and to that of normal dogs. 14 normal dogs and...

Autoregulation of Blood Flow: Vessel Diameter Changes in Response to Different Temperatures

Background: Autoregulation of blood flow is a marvelous phenomenon balanc- ing blood supply and tissue demand. Although many chemically-based explanations for this phenomenon have been proposed and some of them are commonly used today, biomechanical aspects of this phenomenon was neglected. The biomechanical aspect provides insights to us to model vessel diameter changes more precisely and comp...
