Comparison of Hemodynamic Performance of Transcatheter Aortic Valve Implantation With Supra-Annular Self-Expanding Versus Balloon-Expandable Valves Assessed by Exercise Cardiovascular Magnetic Resonance

      Transcatheter aortic valve implantation (TAVI) has recently been approved for low surgical risk patients.

      Transcatheter aortic-valve replacement with a self-expanding valve in low-risk patients.
      Considering that such patients are more likely to engage in active lifestyles, achieving optimal hemodynamics may significantly impact their quality of life. Although previous studies using echocardiography at rest have demonstrated that supra-annular self-expandable valves (SASEVs) (Evolut PRO+, Medtronic, Minneapolis, Minnesota) are associated with favorable hemodynamics compared with balloon-expandable valves (BEVs) (Sapien 3 Ultra, Edwards Lifesciences, Irvine, California),
