Abstract
A finite element (FE) approach was developed to simulate the implantation and function of a Transcatheter Aortic Valve (TAV) device within an MRI-based aortic root model with valvular calcifications. Post-implantation TAV configuration and dynamics well agreed with in vivo imaging data. Contact forces on the surrounding biological structures were consistent with the device specifications. The presence of calcific aortic leaflets led to an asymmetric stent deployment with localized stress concentrations, suggesting the importance of including calcifications in modeling TAV through FE analysis.
