Geographically available, willing to comply with follow up and able to provide written informed consent
Symptomatology due to aortic stenosis resulting in a New York Heart Association (NYHA) Functional Classification of II or greater
75 years of age or older
Aortic valve annular diameter ≥ 21 and ≤23mm measured by MSCT
Echocardiographic or hemodynamic based evidence of calcific (senile) aortic stenosis with one of the following: aortic valve EOA <1.0 cm2 or 0.6 cm2/m2 , mean aortic valve gradient >40 mmHg or peak aortic valve velocity >4 m/sec
An STS score ≥10; or Logistic EuroScore I ≥ 15; or a determination by one cardiovascular surgeon and one cardiologist that the co-morbidities not captured by the STS or EuroScore expected to increase the operative mortality risk to > 15%.

Exclusion Criteria

Congenital unicuspid or bicuspid aortic valve, or noncalcified aortic valve; or valve eccentricity (calcific or otherwise) that in the opinion of the investigator could compromise procedural success.
Unfavorable peripheral vascular anatomy or disease (e.g. severe obstructive calcification, severe tortuosity or small vessels) that would preclude passage of catheters from the femoral arterial access to the aorta as evidenced by peripheral MSCT
Pre-existing prosthetic heart valve in any position, or prosthetic ring

Pre-existing prosthetic heart valve in any position, or prosthetic ring
Moderate to severe mitral stenosis
Life expectancy < 1 year due to non-cardiac co-morbid conditions
Echocardiographic evidence of intracardiac mass, thrombus or vegetation
History of any cognitive or mental health status that would interfere with study participation
Currently participating in any investigational drug or device studies that may confound the results of this study
Untreated clinically significant coronary artery disease requiring revascularization
Patient ineligible for or refuses blood transfusions
Blood dyscrasias defined as: acute leukopenia, acute anemia, acute thrombocytopenia, history of bleeding diathesis or coagulopathy
Need for emergent surgery or intervention other than the investigational procedure
Renal insufficiency as demonstrated by a serum creatinine > 2.5 mg/dL or end stage renal disease requiring chronic dialysis
Severe (Grade 3 to 4) aortic, mitral or tricuspid valve regurgitation
LVEF < 30%
Myocardial infarction within the past 30 days*
Active infection requiring ongoing treatment
Hemodynamic instability requiring inotropic drug therapy within the past 14 days or mechanical support within the past 6 months*
Presence of significant aortic disease such as atheroma, thrombus, or aneurysm which, in the opinion of the investigator, precludes safe implant delivery
Hypersensitivity or contraindication to procedural medication and device materials (e.g. titanium, nickel, pork) which cannot be adequately pre-medicated
Any therapeutic invasive cardiac procedure performed or planned to perform within 30 days of the index procedure, (or 6 months for drug eluting coronary stent or biventricular pacemaker implantation)*
Uncontrolled hypertension (i.e. blood pressure at baseline > 140 mmHg systolic; or in the opinion of the investigator cannot be controlled by medical therapy).
Stroke or transient ischemic attack within past 6 months*
Active peptic ulcer or gastrointestinal bleeding within the past 90 days*
Severe pulmonary hypertension with pulmonary systolic pressure greater than two-thirds of systemic pressure
