In the thesis titled “Preoperative planning and simulation for artificial heart implantation surgery” Sophie Collin, phd of University of Rennes, shows as it’s possible the elaboration of a heart beating model with our Add-on for ANSYS Fluent.
The RBF mesh morphing can be used, with success, to warping process in order to match the meshes describing the structure of interest at each cardiac phase, and the Ansys Fluent to compute the motion vector field to apply to the CFD mesh.
Abstract
Mechanical Circulatory Support (MCS) therapy is increasingly considered for patients with advanced heart failure unresponsive to optimal medical treatments. In this context, we: 1) presented an overview of clinical issues raised by MCS implantation, 2) designed a novel computer-assisted approach for planning the implantation, 3) implemented a CFD model to understand the ventricle hemodynamics induced by the inflow cannula pose. With the aim of decreasing complications and morbidity, quantitative criteria for optimizing ventricle unloading could be determined through CFD, and the planning approach may provide valuable information for choosing the device and adapting the clinical strategy.
