Exclusion Criteria

• •1. 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.
• •2. Pre-existing prosthetic heart valve in any position, or prosthetic ring
• •3. Severe (Grade 3 to 4) aortic, mitral or tricuspid valve regurgitation
• •4. Moderate to severe mitral stenosis
• •5. Myocardial infarction within the past 30 days\*
• •6. Echocardiographic evidence of intracardiac mass, thrombus or vegetation
• •7. LVEF \< 30%
• •8. Uncontrolled hypertension (i.e. blood pressure at baseline \> 140 mmHg systolic ; or in the opinion of the investigator cannot be controlled by medical therapy).
• •9. Severe pulmonary hypertension with pulmonary systolic pressure greater than two-thirds of systemic pressure
• •10. Hemodynamic instability requiring inotropic drug therapy within the past 14 days or mechanical support within the past 6 months\*
• •11. Untreated clinically significant coronary artery disease requiring revascularization
• •12. Presence of significant aortic disease such as atheroma, thrombus, or aneurysm which, in the opinion of the investigator, precludes safe implant delivery
• •13. Blood dyscrasias defined as: acute leukopenia, acute anemia, acute thrombocytopenia, history of bleeding diathesis or coagulopathy
• •14. Patient ineligible for or refuses blood transfusions
• •15. 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
• •16. Active peptic ulcer or gastrointestinal bleeding within the past 90 days\*
• •17. Stroke or transient ischemic attack within past 6 months\*
• •18. Renal insufficiency as demonstrated by a serum creatinine \> 2.5 mg/dL or end stage renal disease requiring chronic dialysis
• •19. Active infection requiring ongoing treatment
• •20. Need for emergent surgery or intervention other than the investigational procedure
• •21. 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)\*
• •22. Hypersensitivity or contraindication to procedural medication and device materials (e.g. titanium, nickel, pork) which cannot be adequately pre-medicated
• •23. Life expectancy \< 1 year due to non-cardiac co-morbid conditions
• •24. Currently participating in any investigational drug or device studies that may confound the results of this study
• •25. History of any cognitive or mental health status that would interfere with study participation \* At the time of procedure, if a subject's medical status has changed since enrollment, the subject shall be re-evaluated for eligibility
