Brief Summary:
This study will evaluate the safety and effectiveness of the Edwards SAPIEN 3/SAPIEN 3 Ultra Transcatheter Heart Valve (THV) compared with clinical surveillance (CS) in asymptomatic patients with severe, calcific aortic stenosis.

Condition or disease Intervention/treatment Phase
Heart Diseases Aortic Stenosis, Severe Device: Edwards SAPIEN 3 / SAPIEN 3 Ultra THV Not Applicable

Detailed Description:
This is a prospective, randomized, controlled, multicenter study. Patients will be randomized 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 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.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. All-cause death, all stroke, and unplanned cardiovascular hospitalization [ Time Frame: When all patients have reached 2-year follow-up ]
    The number of patients that have any of these conditions


Secondary Outcome Measures :
  1. Composite of 1) alive, 2) Kansas City Cardiomyopathy Questionnaire (KCCQ) score ≥75 and 3) KCCQ decrease ≤10 points [ Time Frame: 2 years ]
    The number of patients that meet all of these criteria

  2. Left Ventricular Health [ Time Frame: 2 years ]
    Echocardiographic measurements that will assess the health of the left ventricle

  3. Change in Left Ventricular Ejection Fraction (LVEF) [ Time Frame: 2 years ]
    The average change in LVEF from baseline

  4. New onset atrial fibrillation [ Time Frame: When all patients have reached 2-year follow-up ]
    The number of patients that develop this condition

  5. Death or disabling stroke [ Time Frame: When all patients have reached 2-year follow-up ]
    The number of patients that have any of these conditions

Ages Eligible for Study:   65 Years and older   (Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. 65 years of age or older
  2. Severe aortic stenosis
  3. Patient is asymptomatic
  4. LV ejection fraction ≥ 50%

Exclusion Criteria:

  1. Patient is symptomatic

  3. Native aortic annulus size unsuitable for sizes 20, 23, 26, or 29 mm THV
  4. Iliofemoral vessel characteristics that would preclude safe placement of the introducer sheath.
  5. Left ventricular outflow tract calcification that would increase the risk of annular rupture or significant paravalvular leak post TAVR
  6. Evidence of an acute myocardial infarction ≤ 30 days before randomization
  7. Aortic valve is unicuspid, bicuspid with unfavorable features for TAVR, or is non-calcified

  10. Pre-existing mechanical or bioprosthetic valve in any position
  11. Symptomatic carotid or vertebral artery disease or successful treatment of carotid stenosis within 30 days of randomization
  12. Leukopenia, anemia, thrombocytopenia, history of bleeding diathesis or coagulopathy, or hypercoagulable states
  13. Hemodynamic or respiratory instability requiring inotropic support, mechanical ventilation or mechanical heart assistance within 30 days of randomization
  14. Hypertrophic cardiomyopathy with obstruction
  15. Cardiac imaging evidence of intracardiac mass, thrombus or vegetation
  16. Inability to tolerate or condition precluding treatment with anti-thrombotic therapy
  17. Stroke or transient ischemic attack within 90 days of randomization
  18. Renal insufficiency and/or renal replacement therapy
  19. Active bacterial endocarditis within 180 days of randomization
