Primary Outcome Measures:

Number of Participants That Experienced One or More Components of the Composite Clinical Endpoint of MCE (Major Cardiovascular Events) [ Time Frame: Entire follow-up (median = 4.35 years) ] [ Designated as safety issue: No ]
Composite endpoint of MCE consists of cardiovascular death, AVR (aortic valve replacement) surgery, CHF(congestive heart failure) as a result of progression of aortic stenosis, nonfatal MI (myocardial infarction), CABG (coronary artery bypass) surgery, PCI (percutaneous coronary intervention), hospitalized unstable angina, and nonhemorrhagic stroke

Secondary Outcome Measures:

Number of Participants That Experienced One or More Components of the Composite Clinical Endpoint of AVE (Aortic Valve Events) [ Time Frame: Entire follow-up (median = 4.35 years) ] [ Designated as safety issue: No ]
Composite endpoint of AVE (aortic valve events) consists of AVR surgery, CHF (as a result of progression of AS), or cardiovascular death
Number of Participants That Experienced One or More Components of the Composite Clinical Endpoint of ICE (Ischemic Cardiovascular Events) [ Time Frame: Entire follow-up (median = 4.35 years) ] [ Designated as safety issue: No ]
Composite endpoint of ICE (ischemic cardiovascular events) consists of cardiovascular death, nonfatal MI, CABG, PCI, hospitalized unstable angina, and nonhemorrhagic stroke
Change From Baseline in Peak Transaortic Jet Velocity [ Time Frame: Baseline to End of follow-up (median = 4.35 years) or pre-aortic valve replacement ] [ Designated as safety issue: No ]
Mean change from baseline in peak transaortic jet velocity
