Abstract

A beam model of a nitinol stent and a shell model of the aortic root anatomy are proposed as a means for accurate, numerically stable, and computationally efficient simulation of transcatheter aortic valve implantation (TAVI). Experimental validation of the stent model and image-based validation of the virtual stent implantation are presented. In a clinical setting, the model can be used to predict stent shape and force distribution after TAVI, which allows for estimating transvalvular flow conditions and paravalvular leakage.
