- Subject agrees to complete all required scheduled follow-up visits.
Exclusion Criteria:
Anatomical
- Anatomy precluding safe placement of DurAVR™ THV
- Pre-existing prosthetic heart valve in any position
- Unicuspid or bicuspid aortic valve
- Severe aortic regurgitation

- Echocardiographic evidence of intracardiac mass, thrombus or vegetation requiring treatment
- Severe basal septal hypertrophy with outflow gradient Clinical
- Evidence of an acute myocardial infarction ≤ 30 days before the intended treatment
- Determined inoperable/ineligible for surgery by the Heart Team
- Any percutaneous coronary or peripheral interventional procedure performed within 30 days prior to the index procedure
- Blood dyscrasias as defined: leukopenia (WBC < 1000mm3), thrombocytopenia (platelet count < 50,000 cells/mm3), history of bleeding diathesis or coagulopathy, or hypercoagulable states
- Untreated clinically significant Coronary Artery Disease (CAD) requiring revascularization
- Cardiogenic shock manifested by low cardiac output, vasopressor dependence, or mechanical hemodynamic support

- Ongoing sepsis, including active endocarditis
- Subject refuses a blood transfusion
- Life expectancy < 12 months due to associated non-cardiac co-morbid conditions
- Other medical, social, or psychological conditions that in the opinion of an Investigator precludes the subject from appropriate consent
- 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)

5. Study Description
Brief Summary
A prospective, non-randomized, single-arm, single-center, first-in-human study designed to evaluate the safety and feasibility of the DurAVR™ THV System in the treatment of subjects with symptomatic severe aortic stenosis.
Detailed Description
The DurAVR™ THV System is a novel balloon-expandable single-piece 3D transcatheter aortic valve.
The study will enroll up to 25 subjects suffering from severe, symptomatic aortic stenosis as determined by a Heart Team. Subjects will be consented for follow-up to 1 year.
