Tricuspid valve annular diameter ≥ 40mm or > 21 mm/m2 as measured by baseline TTE in a 4-chamber view within 90 days prior to index implant procedure. 3. Age ≥ 18 years old at the time of enrollment. 4. New York Heart Associate Classification ≥ II. 5. Symptoms of right heart failure despite optimized medical therapy. 6. Multidisciplinary heart team (minimum of four physicians, including imaging, Structural Heart Disease Interventionalist, Heart Failure Cardiologist, and Cardiac Surgeon) agree that percutaneous tricuspid annuloplasty is a reasonable treatment. 7. Left Ventricular Ejection Fraction (LVEF) ≥ 30% within 90 days prior to index implant procedure 8. The subject has suitable anatomy for investigational device implantation as per imaging requirements. 9. The subject has read and signed the informed consent prior to study related procedures. 10. The subject is willing and able to comply with all required follow-up evaluations and assessments.
Exclusion Criteria
- Acute decompensated heart failure requiring hospital admission with 4 weeks of enrollment. 2. Severe RV dysfunction as assessed by echocardiography. 3. Primary (organic) tricuspid pathology (e.g. rheumatic, congenital, infective, etc.). 4. Currently participating in another investigational drug or device study. 5. Systolic pulmonary arterial pressure (sPAP) > 70 mmHg as measured by Transthoracic Echocardiography (TTE). 6. Subject requiring another cardiac procedure in the framework of the index procedure; subject requiring a percutaneous procedure within 30 days before or after the procedure or a cardiac surgical procedure within 3 months before or after the procedure. 7. Tricuspid valve stenosis. 8. Aortic, mitral and/or pulmonic valve stenosis and/or regurgitation more than moderate. 9. Intra-cardiac thrombus, mass or vegetation requiring active treatment. 10. Prior tricuspid repair or tricuspid replacement. 11. Known allergy to contrast media, stainless steel or nitinol that cannot be adequately pre-medicated. 12. History of cardiac transplantation. 13. Contraindication to Transthoracic/Transesophageal Echocardiography (TTE/TEE). 14. Endocarditis or severe infection within 12 months of scheduled implant procedure. 15. Myocardial Infarction (MI), percutaneous coronary intervention (PCI), or known unstable angina within the 60 days prior to the index procedure. 16. Cerebro-Vascular Accident within the previous 3 months. 17. Hemodynamic instability or on IV inotropes. 18. Contraindication to anticoagulant therapy and dual antiplatelet therapy. 19. Documented history of bleeding diathesis, hypercoagulable or active peptic ulcer or gastrointestinal bleeding within 3 months of scheduled implant procedure. 20. Severe renal impairment or on dialysis. 21. Any condition that, in the opinion of the investigator, may render the subject unable to complete the study (e.g. life expectancy < 1 year), or lead to difficulties for subject compliance with study requirements. 22. Acute anemia. 23. Chronic Oral Steroid Use ≥ 6 months. 24. Pregnant or lactating female of childbearing potential with a positive pregnancy test 24 hours before any study-related radiation exposure. 25. Pulmonary embolism within the last 6 months. 26. Tricuspid Valve Tethering distance > 10 mm. 27. Presence of transvalvular pacemaker or defibrillator leads which are determined as immobile or interfering with the procedure, as evaluated by echocardiography. 28. Inadequate TEE acoustic window for appropriate visualization of the tricuspid valve that is required for guiding the index implant procedure. 29. Contra-indicated for blood transfusion or refuses transfusion. 30. Patient undergoing emergency treatment. 31. Patient without appropriate jugular access.

Detailed Description
An early feasibility, multi-center, prospective, single-arm, non-randomized study to assess the safety and performance of the CI Percutaneous Ring Annuloplasty System in patients suffering from ≥ moderate functional tricuspid regurgitation (FTR). Additional outcomes include short and long-term changes in echocardiographic, functional, and quality of life parameters post-adjustment. The CI Ring Annuloplasty System is a percutaneous transcatheter repair device delivered by right heart catheterization through the right internal jugular vein. The System is designed to perform annuloplasty using a Ring Delivery System (RDS) to place a complete, flexible ring over the tricuspid annulus on the atrial side of the valve. Fluoroscopy and transesophageal echocardiography are used to guide and monitor the ring placement procedure. After implantation, the ring becomes embedded within the fibrous tissue of the tricuspid annulus. Approximately 3 months following implantation, the ring is manually adjusted under echocardiographic and fluoroscopic imaging using an Adjustment Tool (AT) until desired reduction of the tricuspid annulus dimension is achieved. Following adjustment, the AT releases a fastener, securing the ring once optimal annular reduction is achieved.
