11. Subject is receiving chronic (=72 hours) anticoagulation therapy (warfarin), and cannot tolerate concomitant therapy with aspirin or clopidogrel (subjects who require chronic anticoagulation must additionally be able to be treated with either aspirin or clopidogrel).*

13. Subject has known hypersensitivity to contrast agents that cannot be adequately pre-medicated, or has known hypersensitivity to aspirin, all thienopyridines, heparin, nickel, titanium, or polyurethanes.
14. Subject has a life expectancy of less than 12 months due to non-cardiac, co-morbid conditions based on the assessment of the investigator at the time of enrollment.
15. Subject has hypertrophic obstructive cardiomyopathy.
16. Subject has any therapeutic invasive cardiac procedure within 30 days prior to the index procedure (except for balloon aortic valvuloplasty and pacemaker implantation which are allowed).
17. Subject has untreated coronary artery disease, which in the opinion of the treating physician, is clinically significant and requires revascularization.
18. Subject has documented left ventricular ejection fraction <30%.
19. Subject is in cardiogenic shock or has hemodynamic instability requiring inotropic support or mechanical support devices.
20. Subject has severe peripheral vascular disease (including aneurysm defined as maximal luminal diameter >5 cm or with documented presence of thrombus, marked tortuosity, narrowing of the abdominal aorta, severe unfolding of the thoracic aorta or thick [>5 mm] protruding or ulcerated atheroma in the aortic arch) or symptomatic carotid or vertebral disease.
21. Femoral artery lumen of <6.0 mm for subjects requiring 23 mm valve size or <6.5 mm for subjects requiring 27 mm valve size, or severe iliofemoral tortuosity or calcification that would prevent safe placement of the introducer sheath.
22. Current problems with substance abuse (e.g., alcohol, etc.).
23. Subject is participating in another investigational drug or device study that has not reached its primary endpoint.
24. Subject has untreated conduction system disorder (e.g., Type II second degree atrioventricular block) that in the opinion of the treating physician is clinically significant and requires a pacemaker implantation.
