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....
