Detailed Description
The purpose of the study is to assess the safety and device performance of the Edwards Tricuspid Transcatheter Repair System in patients with clinically significant, symptomatic, tricuspid regurgitation who are at high surgical risk for standard tricuspid repair/replacement. The study is a multi-center, international, prospective, single arm, safety study. Enrolled subjects will be assessed for clinical follow-up at 1 month, 6 months, 1 year and annually for 3 years post implant procedure.

Outcome Measures
Primary Outcome Measures
- Mortality [At 30 days.]
The primary endpoint for the study will assess the mortality (cardiac) of the as treated cohort at 30 days compared to a literature derived Performance Goal based on high-risk surgical outcomes for tricuspid repair/replacement.
Secondary Outcome Measures
- Technical Success [Implant Procedure]
Alive, with Successful access, delivery and removal of the delivery systems, and Deployment and correct positioning of the intended device, and No need for additional emergency surgery or re-intervention related to the device or access procedure
- Device Success [At 1 month, 6 months, 1, 2 and 3 years]
Alive, with Original intended device in place, and No additional surgical or interventional procedures related to the device, and Tricuspid Regurgitation (TR) reduction compared to baseline and Tricuspid Valve (TV) gradient ≤ 5 mmHg
- Procedural Success Device Success, and [At 1 month]
None of the following device or procedure related Serious Adverse Events (SAE): Life threatening bleeding Major vascular or cardiac structural complications requiring intervention Pericardial effusion requiring drainage or surgery (includes tamponade) Stage 2 or 3 acute kidney injury (includes new dialysis). Severe heart failure or hypotension requiring Intravenous (IV) inotrope, ultrafiltration or mechanical circulatory support Prolonged intubation > 48 hours
- Clinical Outcomes [Heart Failure Re-Hospitalization Rates] [At 1 month, 6 months, 1, 2 and 3 years]
Re-hospitalization rates for the underlying condition (heart failure)
- Clinical Outcomes [Tricuspid Regurgitation Re-Intervention Rates] [At 1 month, 6 months, 1, 2 and 3 years]
Re-intervention rates for the underlying condition (tricuspid regurgitation)
- Clinical Outcomes [Changes in Peripheral Edema] [At 1 month, 6 months, 1, 2 and 3 years]
Change in peripheral edema as assessed by subject weight loss (kilograms) from baseline
- Clinical Outcomes [Change in New York Heart Association (NYHA) Class] [At 1 month, 6 months, 1, 2 and 3 years]
Change in New York Heart Association (NYHA) Class from baseline
- Clinical Outcomes [Change in 6 Minute Walk Test Distance] [At 1 month, 6 months, 1, 2 and 3 years]
Change in 6 minute walk test distance (meters) from baseline
- Clinical Outcomes [Change in Quality of Life Short Form (SF)-12 Questionnaire] [At 1 month, 6 months, 1, 2 and 3 years]
Change in Quality of Life as assessed by the Short Form (SF)-12 questionnaire from baseline
- Clinical Outcomes [Change in Quality of Life Kansas City Cardiomyopathy Questionnaire (KCCQ)] [At 1 month, 6 months, 1, 2 and 3 years]
Change in Quality of Life as assessed by the KCCQ questionnaire from baseline
