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