Brief Summary:
This clinical trial is a prospective, randomized, controlled, multi-center study. Patients will be randomized 1:1 to receive either transcatheter aortic valve replacement (TAVR) with the Edwards SAPIEN 3 / SAPIEN 3 Ultra THV or clinical surveillance. Patients will be stratified by whether or not they are able to perform a treadmill stress test. Patients who have a positive stress test will be followed in a registry to collect data on subsequent treatment and mortality, as applicable.

Primary Outcome Measures :
  1. Freedom from a non-hierarchical composite of all-cause death, all stroke, and unplanned cardiovascular hospitalization. [ Time Frame: 2 years ]
    For the analysis, the trial arms will be compared using the log-rank test.

Secondary Outcome Measures :
