Key result
Patient-specific Finite Element Analysis simulations demonstrated that both valve size and the anatomical asymmetry of the Valsalva sinuses affect the stentless prosthesis placement procedure.
Patient-specific Finite Element Analysis can simulate stentless aortic valve implantation, highlighting the impact of valve size and sinus asymmetry on placement.

Simulations may aid planning of stentless valve implantation; leaves open whether size and asymmetry improve clinical outcomes.
Auricchio et al. (2011) studied Aortic valve leaflet disease. Patient-specific Finite Element Analysis (FEA) for pre-operative planning was evaluated on Prosthesis placement, diastolic closure (coaptation and stress/strain state). Patient-specific Finite Element Analysis simulations demonstrated that both valve size and the anatomical asymmetry of the Valsalva sinuses affect the stentless prosthesis placement procedure.
