Transcatheter aortic valve (TAV) implantation is an established minimally invasive alternative to surgical valve replacement for the treatment of aortic stenosis. Further studies are currently being conducted to increase TAV treatment effectiveness and safety. Within this context, finite element analysis represents an eligible tool to address these challenges. Computational modeling can be adopted to both support the device design phase, reducing times and costs associated with the development cycle, and predict the TAV implantation outcomes, improving the treatment results. In this study, the recently developed Portico TAV (Abbott, USA) was modeled and compared to the commercially available CoreValve TAV (Medtronic, Ireland), by simulating the deployment of the devices in three different idealized aortic root anatomy models through finite element (FE) analyses.
