To evaluate the safety and effectiveness of the JenaValve Trilogy™ Heart Valve System for transcatheter aortic valve replacement (TAVR) in subjects with continuous flow left ventricular assist devices (cfLVAD) and clinically significant aortic regurgitation (AR) who are indicated for TAVR

Inclusion Criteria:

1. Subjects >=18 years of age with continuous flow LVAD (cfLVAD) with clinically significant AR1 leading to cfLVAD dysfunction using cfLVAD ASE guidelines that utilize contemporary management strategies for measurement of AR in patients with cfLVAD2,3:

   • AR is graded from 0 to 6 (0 = none; 1 = trace; 2 = mild; 3 = mild-to-moderate; 4 = moderate; 5 = moderate-to-severe; 6 = severe). Considering that AR during continuous flow LVAD (cfLVAD) support is generally both systolic and diastolic, AR is deemed significant if graded ≥ 3.1

2. Patient with NYHA functional class III/IV

3. Patient with high risk for SAVR as documented by Heart Team.

4. Patient has suitable anatomy to accommodate the insertion and delivery of the JenaValve Trilogy™ Heart Valve System

5. Patient or the patient's legal representative has provided written informed consent

6. Patient or the patient's legal representative agrees to comply with all required post-procedure follow-up visits

Exclusion Criteria:

1. Congenital uni- or bicuspid (Sievers 0) aortic valve morphology
2. Previous prosthetic aortic valve (bioprosthesis or mechanical) implant
3. Mitral regurgitation > moderate
4. Clinically significant coronary artery disease (CAD) requiring revascularization within 30 days prior to index procedure, or planned CAD revascularization procedure within 12 months after index procedure
5. Echocardiographic or CT evidence of left ventricular or aortic valve thrombus
6. Ongoing sepsis or active infective endocarditis with ongoing antibiotic (including suppressive) therapy or positive blood cultures within 6 weeks
7. Hypertrophic cardiomyopathy with or without obstruction
8. Severe pulmonary hypertension (systolic PA pressure >80 mmHg)
9. Decompensated right heart failure as assessed clinically and, if available, by baseline right heart catheterization hemodynamics (e.g., right atrial pressure > pulmonary capillary wedge pressure and cardiac index < 2.5 L/min/m2
10. Severe RV dysfunction as assessed clinically and by echocardiography
11. Aortic annular diameter of <21.0 mm or > 28.6 mm (assessed by Multi-detector CT measurement)
12. Aortic annulus angulation > 70° (assessed by Multi-detector CT measurement)
13. Straight length of ascending aorta of < 55 mm
14. Significant disease of ascending aorta, including ascending aortic aneurysm (defined as maximal luminal diameter of 50 mm or greater) or atheroma (including if thick [>5 mm], protruding or ulcerated)
15. Myocardial infarction < 30 days prior to index procedure
16. Cerebrovascular event (TIA, stroke) < 180 days prior to index procedure
17. Blood dyscrasias as defined: leukopenia (WBC < 3000/mm³), or thrombocytopenia (platelets < 90,000/μl) or anemia (Men: Hgb < 8.1 g/dl; Women: Hgb < 7.4 g/dl)
18. Active peptic ulcer or upper gastrointestinal bleeding < 90 days prior to index procedure
19. Known hypersensitivity or contraindication to aspirin, heparin, ticlopidine or clopidogrel, nitinol, tantalum or allergy to contrast agents that cannot be premedicated
20. Subject unable to undergo pre-procedure transesophageal echocardiography or Multi-Detector CT (MDCT) scan for aortic annular sizing
21. Patient is enrolled in another investigational medical device or drug study which has not completed the required primary endpoint follow-up. (Note: Patients involved in a long-term surveillance phase of another study are eligible for enrollment in this registry)
