A fast in silico model for preoperative risk assessment of paravalvular leakage

A workflow to perform fast preoperative risk assessment of paravalvular leakage (PVL) after transcatheter aortic valve replacement (TAVR) is presented in this paper. Physiological pressure and flow conditions in the aortic root are generated using a commercial pulse duplicator system from ViVitro Labs Inc. (Victoria, Canada). This model can be used to calculate the regurgitant volume after TAVR at reduced cost.
