Importance of prosthetic valve hemodynamics in the low risk AS population following TAVR or SAVR-

Learning objectives:
1- Describe the role and evolution of TAVI in the low risk population and in the patients with a small annulus.
2- Raise the importance of valve hemodynamics following TAVI or SAVR in the low risk population.
3- Use appropriate methods to measure transvalvular pressure gradients and effective orifice area (EOA) by echo.
4- Apply the methods and criteria to identify and quantify prosthesis-patient mismatch, structural and non-structural bioprosthetic valve dysfunction.
