Early Feasibility Study of the Percutaneous 4Tech TriCinch Coil Tricuspid Valve Repair System
Study Details
Study Description
Brief Summary
The primary objective of the study is to generate feasibility safety and performance data for the 4Tech TriCinch Coil System in symptomatic patients suffering from moderate to severe functional tricuspid regurgitation with annular dilatation.
The TriCinch Coil System is a percutaneous catheter-based medical device for tricuspid valve repair.

Device: Tricinch Coil System Implantation
Patients enrolled in this study with all eligibility criteria confirmed will be implanted with the TriCinch Coil System. This device offers a percutaneous treatment (access through the vein at the groin) to treat the leaking tricuspid valve.

Outcome Measures
Primary Outcome Measures
- All-cause mortality of the Per Protocol cohort at 30 days post procedure. [30 days post procedure]
Secondary Outcome Measures
- Number of individual adverse events related to the system or procedure. [30 days, three (3), six (6), twelve (12) and twenty-four (24) months post procedure]
- Echocardiographic changes in Effective Regurgitant Orifice Area (EROA) compared to Baseline [30 days, three (3), six (6), twelve (12) and twenty-four (24) months post procedure]
as assessed by the flow convergence method
- Functional changes as compared to Baseline for New York Heart Association (NYHA) classification [30 days, three (3), six (6), twelve (12) and twenty-four (24) months post procedure]
The severity of patients' heart failure symptoms is assessed using the New York Heart Association (NYHA) classification. Patients are ranked from Class I (no limitation of physical activity) to Class IV (unable to carry on any physical activity without discomfort).
- Rate of Heart Failure event post-procedure defined as a heart failure hospitalization or a heart failure hospitalization equivalent [30 days, three (3), six (6), twelve (12) and twenty-four (24) months post procedure]
- Exercise tolerance (Six Minute Walk Test) [30 days, three (3), six (6), twelve (12) and twenty-four (24) months post procedure]
- Quality of Life evaluation using the Kansas City Cardiomyopathy Questionnaire (KCCQ). [30 days, three (3), six (6), twelve (12) and twenty-four (24) months post procedure]
The Kansas City Cardiomyopathy Questionnaire (KCCQ) is a 23-item, self-administered instrument that quantifies physical function, symptoms (frequency, severity and recent change), social function, self-efficacy and knowledge, and quality of life. In the KCCQ, an overall summary score can be derived from the physical function, symptom (frequency and severity), social function and quality of life domains. Scores are transformed to a range of 0-100, in which higher scores reflect better health status.
