Fluid-structure interaction modeling of aortic valve stenosis at different heart rates.

Purpose: This paper proposes a model to measure the cardiac output and stroke volume at different aortic stenosis severities using a fluid-structure interaction (FSI) simulation at rest and during exercise.

Methods: The geometry of the aortic valve is generated using echocardiographic imaging. An Arbitrary Lagrangian-Eulerian mesh was generated in order to perform the FSI simulations.
