In-vivo Validation of a Stent Implantation Numerical Model

A large deformation finite element model for the patient-specific prediction of stent implantation is presented as a potential tool to assist clinicians. The intervention simulation includes the complete stent deployment under balloon inflation and deflation in the artery. This paper describes the proposed model and presents an in-vivo validation of the model using pre- and post-intervention data from a patient who underwent stent implantation. Predicted cross-section areas at different artery positions are compared to post-intervention measurements. This work demonstrated the model's potential to become a relevant tool for predicting the arterial response to the intervention.
