NHLBI and Cook Trans-Atrial Intra-Pericardial Tricuspid Annuloplasty (TRAIPTA) Early Feasibility Study
- Conditions
- Tricuspid Valve Insufficiency
- Interventions
- Device: TRAIPTA (Trans-Atrial Intra-Pericardial Tricuspid Annuloplasty)
- Registration Number
- NCT06479824
- Brief Summary
Background:
Tricuspid valve regurgitation is a disease where one of the heart valves leaks. The leak affects blood flow. People with this disease may feel breathless and lack energy; they may need to stay in the hospital when fluid builds up in the body. The tricuspid is the most difficult valve to repair with surgery. Researchers want to try a new procedure called trans-atrial intra-pericardial tricuspid annuloplasty (TRAIPTA).
Objective:
To test TRAIPTA in people with tricuspid valve regurgitation.
Eligibility:
Adults aged 21 years and over with tricuspid valve regurgitation. They must not be eligible for standard surgical repair.
Design:
Participants will be screened. They will have tests of their heart function; these will include blood tests, imaging scans, and a 6-minute walking test.
Participants will enter the hospital for at least 1 day. The TRAIPTA procedure will be done under sedation or general anesthesia. The TRAIPTA study device is a loop that will be placed around the heart like a belt. It acts like a lasso to reduce leakage of the heart valve. Doctors will put the device in place by inserting a wire through a vein in the leg; they will thread the device up to the heart through the vein. The wire will be removed, but the TRAIPTA device will remain in place.
Participants will have follow-up visits 4 times in 1 year after the procedure. These visits will include physical exams, blood tests, imaging scans, and other tests of heart function.
Researchers will contact participants or their doctors for heart test results for another 4 years....
- Detailed Description
Study Description:
Functional tricuspid valve regurgitation is common, has high morbidity and mortality, and has no good treatments. We developed a new transcatheter treatment for this orphan disease called TRAIPTA (Trans-Atrial Intra-Pericardial Tricuspid Annuloplasty). In TRAIPTA, catheter tools cross the wall of the heart to enter the pericardial space surrounding the heart, encircle the heart around the atrioventricular groove, and apply tension to reshape and narrow the heart to help the leaky tricuspid valve to function better. After placing the belt, a closure device is deployed to close the puncture in the right atrial appendage.
This is the first human test of the TRAIPTA technique. It is offered to patients who are suffering from clinically significant tricuspid valve regurgitation and who have no other good treatment options.
Objectives:
The objectives of this study are to test whether TRAIPTA is feasible, safe, favorably remodels tricuspid annular geometry, and reduces severity of functional tricuspid valve regurgitation.
Primary Safety Endpoint:
The primary endpoint is safety, measured as a composite of freedom from major adverse cardiovascular events (MACE) assessed at 30 days after the TRAIPTA procedure, including all of the following:
* All-cause Mortality
* Stroke (disabling and non-disabling)
* Device-related pulmonary thromboembolism (symptomatic)
* TRAIPTA-related coronary compression requiring coronary revascularization or post-procedure relief of TRAIPTAcompression
* Pericardial tamponade. Note that insertion of a pericardial drain and pericardial effusion requiring drainage is an expected part of the TRAIPTA procedure, and does not contribute to the primary safety endpoint.
* Major cardiac structural related complications including cardiac surgery related to the device.
* Major access site and vascular complications
* Acute kidney injury requiring new renal replacement therapy.
* Bleeding (major or worse) according to MVARC
Secondary (Performance) Endpoints:
The performance endpoints are secondary, and are assessed at the timepoints indicated.
* Technical success (measured at exit from cath lab). All the following must be present:
* Absence of procedural mortality; and
* Successful access, delivery, and retrieval of the TRAIPTA Delivery System; and
* Successful deployment and correct positioning of the TRAIPTA annuloplasty belt; and
* Freedom from emergency surgery or reintervention related to the TRIAPTA or access procedure.
* Device success (measured at 30 days). All of the following must be present:
* Absence of procedural mortality or stroke; and
* Proper placement and positioning of the TRAIPTA annuloplasty belt; and
* Freedom from unplanned surgical or interventional procedures related to the device or access procedure; and
* Safety of the TRAIPTA annuloplasty belt, including:
* No evidence of structural or functional device failure
* No specific device-related technical failure issues and complications
* Reduction of TR by at least one degree without significant tricuspid valve stenosis.
