Inclusion Criteria:

- For asymptomatic patients:
Very severe aortic stenosis with an aortic valve area of ≤1.0 cm2 (or aortic valve area index of ≤0.6 cm2/m2), AND maximal aortic velocity ≥5.0 m/sec, or mean gradient ≥60 mmHg by transthoracic echocardiography at rest, OR
Aortic valve area of ≤1.0 cm2 (or aortic valve area index of ≤0.6 cm2/m2), AND a mean gradient ≥40 mmHg or maximal aortic valve velocity ≥4.0 m/sec by transthoracic echocardiography at rest, AND an exercise tolerance test that demonstrates a limited exercise capacity, abnormal BP response, or arrhythmia OR
Aortic valve area of ≤1.0 cm2 (or aortic valve area index of ≤0.6 cm2/m2), AND mean gradient ≥40 mmHg, or maximal aortic valve velocity ≥4.0 m/sec by transthoracic echocardiography at rest, AND a left ventricular ejection fraction <50%.
- Patient is considered low risk for SAVR, where low risk is defined as predicted risk of mortality for SAVR <3% at 30 days per multidisciplinary local heart team assessment.

- The subject and the treating physician agree that the subject will return for all required post-procedure follow-up visits.
Exclusion Criteria:
- Any condition considered a contraindication for placement of a bioprosthetic valve (eg, subject is indicated for mechanical prosthetic valve).
- Age less than 60 years
A known hypersensitivity or contraindication to any of the following that cannot be adequately pre-medicated:
- aspirin or heparin (HIT/HITTS) and bivalirudin
- ticlopidine and clopidogrel

- Estimated life expectancy of less than 24 months due to associated non-cardiac co-morbid conditions.
- Other medical, social, or psychological conditions that in the opinion of the investigator precludes the subject from appropriate consent or adherence to the protocol required follow-up exams.
