WebOct 10, 2024 · Methods. Simulations were performed using finite element models of the LV + mitral valve based on MRI of 5 sheep with FMR-CAD. Models were modified to have a 20% increase in LV volume (↑LV_VOLUME) and MitraClip was simulated with contracting beam elements (virtual sutures) placed between nodes in the center edge of the anterior … WebJul 2, 2013 · In this study, the effects of the stentless valve design on leaflet stress were investigated with a finite element model. Methods Finite element models of the stentless quadrileaflet mitral valve were created in the close and open configurations. The geometry of the stented trileaflet mitral valve was also analyzed for comparative purposes.

Webmolecular/cellular computer code into my finite element framework.I have also worked on developing an approach that can be used to identify the mechanical properties of the mitral valve leaflets. This is accomplished by using a combination of experimental measurements and computational modeling. This validated model can WebWe aim at testing the possibility to build patient-specific structural finite element models (FEMs) of the mitral valve (MV) from cardiac magnetic resonance (CMR) imaging and to use them to ... WebJul 4, 2008 · Here, a new computational model of the mitral valve has been developed from in vivo data, as a first step towards the development of patient-specific models for the evaluation of annuloplasty procedures. A structural finite-element model of the mitral valve has been developed to account for all of the main valvular substructures. bauma albert
