J-Valve to Treat Aortic Regurgitation Via Transcatheter Therapy

This is a prospective, single arm, multi-center, interventional pivotal study that will enroll up to 194 subjects in up to 35 investigational sites, predominantly in the United States and up to 7 in Canada, Europe, and Japan. Of the 194 subjects, the CMR imaging sub-study will include up to 75 subjects with severe AR already confirmed by TTE. Additionally, up to 40 roll-in subjects may be treated to enable clinical experience and exposure to the device while allowing a reasonable learning curve. The subjects will then be followed 5-years post-procedure of the J-Valve TF System.

Sex: ALL
Minimum Age: 18 Years
Healthy Volunteers: No
Age Groups: ADULT, OLDER_ADULT

Inclusion Criteria:

1. Symptomatic according to New York Heart Association (NYHA) functional class (FC) II or higher
2. Severe AR, defined as follows, as assessed by Imaging Core Laboratory:

A. Severe AR by Transthoracic Echocardiography (TTE) (grade 3 or 4)

B. OR, if indeterminate AR, by TTE, ANY ONE of the following:

i. Cardiac magnetic resonance imaging (CMR)-derived aortic regurgitant fraction (RF) ≥43% ii. CMR-derived RF ≥33% + left ventricular dilation (left ventricular end diastolic volume index [LVEDVi]) >105 mL/m^2 for men or LVEDVi >96 mL/m^2 for women) iii. CMR-derived RF ≥33% + LV ejection fraction (LVEF) ≤55% or left ventricular end systolic volume index (LVESVi) ≥43mL/m^2; iv. Severe AR by Transesophageal Echocardiography (TEE) (grade 3 or 4)
3. High risk for surgery as judged by a multi-disciplinary heart team
4. Suitable anatomy to accommodate the insertion, delivery, and deployment of the study devices (see anatomic exclusions below)
5. Written informed consent and agreement to comply with all required post-procedure follow-up visits at investigational site.

Exclusion Criteria:

1. Previous prosthetic aortic valve (bioprosthesis or mechanical) implant
2. Aortic valve stenosis > moderate*
3. Severe mitral valve or tricuspid valve regurgitation*
4. Severe mitral valve or tricuspid valve stenosis*
5. Active infection, including infective endocarditis
6. Cardiac imaging evidence of cardiac mass, thrombus or vegetation
7. Inability to tolerate or a condition precluding treatment with antithrombotic (antiplatelet, anticoagulant) therapy
8. Renal insufficiency (eGFR <30 mL/min/1.73m^2) or end stage renal disease requiring chronic dialysis
9. Liver disease (cirrhosis of the liver [Child-Pugh Class B or C])
10. Blood dyscrasias as defined: leukopenia (WBC <3000 cells/mcL), thrombocytopenia (platelet count <50,000 cells/mcL), anemia (hemoglobin <9 g/dL), history of bleeding diathesis coagulopathy, or hypercoagulable state (unless therapeutically stable)
11. Known hypersensitivity or contraindication to aspirin, heparin, bivalirudin, clopidogrel, Nitinol (Nickel, Titanium) or sensitivity to contrast media, which cannot be adequately premedicated
12. Left ventricular dysfunction with left ventricular ejection fraction (LVEF) 70mmHg or systolic PA pressure ≥2/3 of systemic systolic BP)
21. Severe chronic obstructive pulmonary disease (COPD) requiring chronic oral steroids or requiring continuous home O2
22. Stroke (CVA), transient ischemic attack (TIA) or neurological signs and symptoms attributed to carotid or vertebrobasilar disease within 90 days prior to index procedure
23. Cardiogenic shock defined as systolic blood pressure 5 cm*
2. Aortic Annulus Perimeter 104 mm*
3. Inappropriate anatomy for femoral introduction and delivery of the study system
4. Left ventricular end-diastolic diameter (LVEDD) >75 mm*
5. Congenital aortic valve disease including Unicuspid, Bicuspid, or Quadricuspid aortic valve anatomy*
6. Congenital univentricle or other condition that, in the opinion of the investigator and/or consulting physician, may constitute an unwarranted surgical risk
7. Excessive aortic valve prolapse that would preclude proper seating of the implant in the aortic annulus
8. Abdominal/thoracic aortic aneurysm ≥5.0 cm*
9. Aorto-iliac disease requiring intervention to facilitate delivery of access sheath
10. Excessive tortuosity of delivery system pathway, defined as severe tortuosity of multiple vessels including iliofemoral, thoracoabdominal aorta, aortic arch, or LV-aortic root angle >80⁰
