    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

    Entire follow-up (median = 4.35 years)

Secondary Outcomes (3)

  • Number of Participants That Experienced One or More Components of the Composite Clinical Endpoint of AVE (Aortic Valve Events)

    Entire follow-up (median = 4.35 years)

  • Number of Participants That Experienced One or More Components of the Composite Clinical Endpoint of ICE (Ischemic Cardiovascular Events)

    Entire follow-up (median = 4.35 years)

  • Change From Baseline in Peak Transaortic Jet Velocity

    Baseline to End of follow-up (median = 4.35 years) or pre-aortic valve replacement

Other Outcomes (13)

  • Cardiovascular Death

    Entire follow-up (median = 4.35 years)

  • Aortic Valve Replacement (AVR)

    Entire follow-up (median = 4.35 years)

  • Congestive Heart Failure (CHF) Due to Progression of Aortic Stenosis (AS)

Limitations and Caveats

It is important to note that several of the ischemic outcomes making up the composite ischemic endpoint can occur as a causal consequence of aortic stenosis progression itself, or in association with its standard treatment (aortic valve replacement).
