Numerical investigation of hemodynamic performance of a stent in the main branch of a coronary artery bifurcation.

The effect of a bare-metal stent on the hemodynamics in the main branch of a coronary artery bifurcation with a particular type of stenosis was numerically investigated by the computational fluid dynamics (CFD). Three-dimensional idealized geometry of bifurcation was constructed in Catia modelling commercial software package. The Newtonian blood flow was assumed to be incompressible and laminar.

Numerical investigation of the blood flow through the middle cerebral artery.

The middle cerebral artery (MCA) is one of the three major paired arteries that supply the blood to the cerebrum. In the present study, the three-dimensional (3D) blood flow in the left MCA was numerically simulated by using the medical imaging. The arterial geometry was obtained by applying the CT angiography of the MCA of a 75-year-old man.
