In plain English
This study is testing a heart device called the J-Valve for people with severe aortic valve regurgitation (when the aortic valve leaks, allowing blood to flow backwards) or mixed aortic valve disease. The valve is placed through a tube inserted into a large artery in the leg (the transfemoral route). The study is sponsored by JC Medical, Inc., an affiliate of Edwards Lifesciences LLC.
Who can take part
- Adults with symptoms such as breathlessness, at New York Heart Association (NYHA) class II or higher
- Severe aortic regurgitation confirmed by heart scans (such as echocardiography or cardiac magnetic resonance imaging)
- Considered high risk for open-heart surgery, as judged by a team of heart specialists
- Heart and blood vessel anatomy suitable for the device being inserted through the leg artery
- Willing to give written informed consent and attend all required follow-up visits at the study site
Who may not be able to
- Already have an artificial aortic valve (tissue or mechanical)
- More than moderate narrowing of the aortic valve
- Severe leaking or narrowing of the mitral or tricuspid heart valves
- Active infection, including infection of the heart valves (endocarditis)
- Cannot take blood-thinning medicines
- Severe kidney problems (very low kidney filtration rate or on long-term dialysis)
- Severe liver disease (certain types of cirrhosis)
- Certain blood disorders, such as very low white cell or platelet counts, severe anaemia, or clotting problems
- Allergy or contraindication to aspirin, heparin, bivalirudin, clopidogrel, nickel or titanium (Nitinol), or contrast dye that cannot be managed with pre-medication
- Very weak heart pumping (left ventricular ejection fraction below 25%)
- Significant untreated coronary artery disease needing a procedure to open the arteries
- Heart attack or artery-opening procedure in the last 30 days
- Carotid artery procedure in the last 6 weeks, or carotid disease needing treatment
- Other surgery or procedures planned shortly before, during, or within 30 days after this procedure
- Uncontrolled atrial fibrillation
- Severe right-sided heart weakness or severe pulmonary hypertension
- Severe chronic obstructive pulmonary disease (COPD) needing long-term steroids or home oxygen
- Stroke, mini-stroke, or related neurological symptoms in the last 90 days
- Cardiogenic shock or needing mechanical heart support in the last 30 days
- Life expectancy under 24 months due to non-heart conditions
- Pregnant or planning pregnancy before completing follow-up
- Taking part in another research study that has not finished its main assessment
- Considered part of a vulnerable group
- Certain anatomy issues, such as an enlarged aorta, aortic size outside the range for the device, an enlarged left ventricle, congenital valve shape differences (one, two, or four leaflet valves), blood vessel twisting or blockage that makes leg access unsuitable, or an aneurysm of 5 cm or more in the chest or belly aorta
What taking part involves
- • A replacement aortic valve (the J-Valve) is placed through a tube inserted into an artery in the leg, without open-heart surgery

About This Trial
The primary objective of this study is to assess the safety and efficacy of the J-Valve Transfemoral (TF) System in patients with symptomatic, severe (grade 3 or 4), native aortic valve regurgitation (AR) and AR-dominant mixed aortic valve disease, who are judged by a multi-disciplinary heart team to be at high risk for open surgical aortic valve replacement (SAVR). A Cardiac Magnetic Resonance (CMR) sub-study will examine if intervention for AR translates to improved ventricular remodeling, the impact of LV remodeling on clinical outcomes and quality of life, as well as volumetric and myocardial differences between genders.
More detail
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.
