Hemodynamic Changes in Coronary Artery after Stent Implantat
Transcript of Hemodynamic Changes in Coronary Artery after Stent Implantat
Wall Shear Stress
After stent implantation, the maximums flow rate decreased to 1.602 m/s.
The areas of high wall shear stress are similar to the high velocity.
The maximum shear stress is decreased in the pre-stenting case than in the post-stenting case.
Stent implantation is a minimally invasive procedure for treatment of coronary artery stenosis.
After stenting, the simulation shows a reduction of wall pressure and wall shear stress and a more equal flow through arteries after stenting. After stenting, the simulation shows a reduction of wall pressure and wall shear stress and a more equal flow through arteries after stenting.
In the post-stenting case, the pressure is much lower compared with pre-stenting case.
Inside the stent, it dropped smoothly before the bifurcation.
Hemodynamic Changes in Coronary Artery after stent Implantation
The aim is to study the hemodynamic changes in coronary artery after stent implantation.
The flow rate in pre- and post-stenting models was measured.
The maximum flow rate before stent implantation was 2.938 m/s.

Coronary arteries are subjected to complex deformation in the cardiac cycle.
Nowadays stent placement becomes a common intervention procedure for treatment of coronary artery disease and its clinical outcome was better when compared to standard angioplasty.
