Comparison of Doppler-based finite element results with computed tomography and/leaflet-specific time-averages major principal stress stress/Doppler-based calibrated material properties- Patient #1. (a) Computed tomographic and Doppler echocardiographic images compared to the results of the Doppler-based finite element solver; (b) the time-averaged maximum principal stress on all native aortic valve leaflets pre-intervention and all transcatheter valve leaflets post-intervention; (c) results of the Doppler-based framework illustrating the material properties and leaflet stiffness as well as performance features such as ejection time and cardiac cycle duration.
