Representation of Plaque — Lesson 2

Arterial plaque can obstruct normal blood flow and stiffen the arteries. The deployment of a stent can help to restore blood flow and maintain the vessel opening. This artistic rendering of a vessel with plaque illustrates in a simple way the development of plaque in the arteries and the obstruction this causes to normal blood flow.

 

In this lecture, we will learn about the characteristics and modeling considerations of coronary artery plaque

Lesson Video — Walk Through Workshop

In this walkthrough workshop, we cover all the necessary steps needed to build a representative geometry of plaque in a blood vessel for use in a stent deployment simulation.

The simulation files for this workshop can be found here.

  • Please utilize the mm, kg, N unit system when solving the Ansys simulation models.
  • Please also note that the results you obtain in these nonlinear analyses may differ slightly from those shown in the videos. Numerical round-off due to finite machine precision can be affected by the choice of the operating system, the number of cores, and the type of parallel processing (shared memory vs. distributed memory). Moreover, nonlinear contact and solution algorithms are often improved in each version of our software, so some changes are expected when comparing results between different releases. Thus, your results may differ slightly (within typical engineering tolerances) from the presented results, but this is to be expected for nonlinear analyses, especially for numerically unstable (e.g., underconstrained) models that may be utilized in this course.

Completed simulation files for the above examples can be found here.
