This is an interventional device feasibility trial for Symptomatic Aortic Stenosis focused on measuring TAVI, TAVR, Transcatheter Aortic Valve Implantation, Transcatheter valve Read More

Inclusion Criteria:

1. Symptomatic, severe aortic stenosis
2. Eligible for delivery of the DurAVR™ THV
3. Anatomy appropriate to accommodate safe placement of DurAVR™ THV
4. Understands the study requirements and the treatment procedures and provides written informed consent.
5. Subject agrees to complete all required scheduled follow-up visits.

Exclusion Criteria:

Anatomical

1. Anatomy precluding safe placement of DurAVR™ THV
2. Pre-existing prosthetic heart valve in any position
3. Unicuspid or bicuspid aortic valve
4. Severe aortic regurgitation
5. Severe mitral or severe tricuspid regurgitation requiring intervention
6. Moderate to severe mitral stenosis
7. Hypertrophic obstructive cardiomyopathy
8. Echocardiographic evidence of intracardiac mass, thrombus or vegetation requiring treatment
9. Severe basal septal hypertrophy with outflow gradient Clinical
10. Evidence of an acute myocardial infarction ≤ 30 days before the intended treatment
11. Determined inoperable/ineligible for surgery by the Heart Team
12. Any percutaneous coronary or peripheral interventional procedure performed within 30 days prior to the index procedure
13. Blood dyscrasias as defined: leukopenia (WBC < 1000mm3), thrombocytopenia (platelet count < 50,000 cells/mm3), history of bleeding diathesis or coagulopathy, or hypercoagulable states
14. Untreated clinically significant Coronary Artery Disease (CAD) requiring revascularization
15. Cardiogenic shock manifested by low cardiac output, vasopressor dependence, or mechanical hemodynamic support
16. Need for emergency surgery for any reason
17. Ventricular dysfunction with left ventricular ejection fraction (LVEF) ≤ 40% as measured by resting echocardiogram
18. Recent (within 6 months) cerebrovascular accident (CVA) or transient ischemic attack (TIA)
19. Symptomatic carotid or vertebral artery disease
20. End stage renal disease requiring chronic dialysis or creatinine clearance < 20 cc/min
21. GI bleeding within the past 3 months
22. A known hypersensitivity or contraindication to any of the following which cannot be adequately pre-medicated: aspirin, heparin, nitinol (titanium or nickel), ticlopidine and clopidogrel, contrast media
23. Ongoing sepsis, including active endocarditis
24. Subject refuses a blood transfusion
25. Life expectancy < 12 months due to associated non-cardiac co-morbid conditions
26. Other medical, social, or psychological conditions that in the opinion of an Investigator precludes the subject from appropriate consent
27. Severe dementia (resulting in either inability to provide informed consent for the trial/procedure, prevents independent lifestyle outside of a chronic care facility, or will fundamentally complicate rehabilitation from the procedure or compliance with follow-up visits)
28. Currently participating in an investigational drug or another investigational device trial
29. Subject belongs to a vulnerable population.
