Eligibility Criteria:
Inclusion Criteria - Severe aortic stenosis, defined as aortic valve area of \< 1.0 cm2 (or aortic valve area index of \< 0.6 cm2/m2) by the continuity equation, AND mean gradient \> 40 mmHg or maximal aortic valve velocity \> 4.0 m/sec by resting echocardiogram.
Subjects with low-flow/low gradient severe aortic stenosis can be included, provided low-dose dobutamine or exercise stress echocardiography demonstrates a mean gradient of \>40 mmHg or a maximal aortic valve velocity of \>4.0 m/sec, AND aortic valve area of \<1.0cm2 (or aortic valve area index of \<0.6 cm2/m2).
* STS score of ≥ 8 OR documented heart team agreement of ≥ high risk for AVR due to frailty or co-morbidities.
* Symptoms of aortic stenosis, AND NYHA Functional Class II or greater
* 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 (e.g. subject is indicated for mechanical prosthetic valve).
* A known hypersensitivity or contraindication to any of the following which cannot be adequately pre-medicated: aspirin or heparin (HIT/HITTS) and bivalirudin, ticlopidine and clopidogrel, Nitinol (titanium or nickel), contrast media
* Blood dyscrasias as defined: leukopenia (WBC \< 1000 mm3), thrombocytopenia (platelet count \<50,000 cells/mm3), history of bleeding diathesis or coagulopathy, or hypercoagulable states.
* Untreated clinically significant coronary artery disease requiring revascularization.
* Severe left ventricular dysfunction with left ventricular ejection fraction (LVEF) \< 20% by echocardiography, contrast ventriculography, or radionuclide ventriculography.
* End stage renal disease requiring chronic dialysis or creatinine clearance \< 20 cc/min.
* Ongoing sepsis, including active endocarditis.
* Any percutaneous coronary or peripheral interventional procedure with a bare metal or drug eluting stent performed within 30 days prior to the study procedure.
* Symptomatic carotid or vertebral artery disease or successful treatment of carotid stenosis within 10 weeks of Heart Team assessment.
* Cardiogenic shock manifested by low cardiac output, vasopressor dependence, or mechanical hemodynamic support.
* Recent (within 6 months of Heart Team assessment) cerebrovascular accident (CVA) or transient ischemic attack (TIA).
* Gastrointestinal (GI) bleeding that would preclude anticoagulation.
* Subject refuses a blood transfusion.
* Severe dementia (resulting in either inability to provide informed consent for the study/procedure, prevents independent lifestyle outside of a chronic care facility, or will fundamentally complicate rehabilitation from the procedure or compliance with follow-up visits).
* Estimated life expectancy of less than 12 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-ups exams.
* Currently participating in an investigational drug or another device study (excluding registries).
* Evidence of an acute myocardial infarction ≤ 30 days before the study procedure.
* Need for emergency surgery for any reason.
* Liver failure (Child-Pugh class C).
* Subject is pregnant or breast feeding.
Anatomical exclusion criteria:
* Pre-existing prosthetic heart valve in any position.
* Mixed aortic valve disease (aortic stenosis with severe aortic regurgitation).
* Severe mitral regurgitation.
* Severe tricuspid regurgitation.
* Moderate or severe mitral stenosis.
* Hypertrophic obstructive cardiomyopathy.
* Echocardiographic or Multi-Slice Computed Tomography (MSCT) evidence of intracardiac mass, thrombus, or vegetation.
* Congenital bicuspid or unicuspid valve verified by echocardiography.
