• Gender: Male or Female

• Other Inclusion Criteria:
  

  1. Subjects who are 65 years of age or older
  2. Subjects must have Severe Aortic Stenosis
  3. Subjects are asymptomatic defined as having negative treadmill stress test or as per physician after thorough assessment of patient history if the patient is unable to perform a stress test.
  4. Subjects have LV ejection fraction ≥50%
  5. Subjects have Society of Thoracic Surgeons (STS) risk score ≤10
  6. Subjects have been informed of the nature of the study, agrees to its provisions and has provided written informed consent

  
  

You may not be eligible for this study if the following are true:
