Trial Summary
What is the purpose of this trial?The Paradigm study is a prospective, multicenter, single arm study to demonstrate the safety and effectiveness of the Amplatzer Valvular Plug III (AVP III) as a treatment for clinically significant PVLs following surgical implant of a mechanical or biological heart valve implanted in the aortic or mitral position.
Do I need to stop my current medications for the trial?
The trial information does not specify whether you need to stop taking your current medications. Please consult with the trial coordinators for more details.
What data supports the effectiveness of the treatment Amplatzer Valvular Plug III for aortic regurgitation?
The Amplatzer Vascular Plug III has been tested in laboratory settings for its ability to close leaks around heart valves, which suggests it might be effective in treating aortic regurgitation by sealing unwanted openings.
12345Is the Amplatzer Plug safe for use in humans?
The Amplatzer Vascular Plug has been used safely in various procedures, such as preventing leaks during aneurysm repair and treating complications in dialysis access, indicating it is generally safe for human use.
13456How is the Amplatzer Valvular Plug III treatment different from other treatments for aortic regurgitation?
The Amplatzer Valvular Plug III is unique because it is a self-expanding device designed to close leaks around heart valves, offering a minimally invasive option compared to traditional surgery. It is specifically used to address paravalvular leaks (gaps around a valve) and is deployed through a catheter, which is a thin tube inserted into the body, making it less invasive than open-heart surgery.
12578Eligibility Criteria
This trial is for adults over 18 with a mechanical or biological heart valve in the aortic or mitral position and significant paravalvular leak causing heart issues or needing blood transfusions. Not eligible if pregnant, nursing, have limited life expectancy, unstable health, other conflicting conditions, or are in another drug/device study.Inclusion Criteria
I have a mechanical or biological valve implant in my heart.
I have a serious heart valve leak causing heart failure or need for regular blood transfusions.
I am 18 years old or older.
I have a heart defect that can be fixed with one device.
Exclusion Criteria
My veins are not suitable for AVP III delivery.
I have leaking around my artificial heart valves.
I cannot have surgery because my heart and blood circulation are not stable.
My heart's structure makes it unsuitable for a specific closure device due to risk of interference or complications.
I cannot take blood thinners during procedures.
I am capable of understanding and consenting to participate in this trial.
My heart valve replacement is significantly loose or malfunctioning.
I have an active infection or endocarditis.
Participant Groups
The PARADIGM study tests the safety and effectiveness of the Amplatzer Valvular Plug III (AVP III) to treat leaks around surgical heart valves. It's a forward-looking single-group study involving multiple centers.
