Brief summary
Pivotal trial to evaluate the safety and effectiveness of the P&F TricValve® Transcatheter Bicaval Valve System.
Detailed description
The study is a prospective, multi-center, randomized controlled pivotal clinical trial to evaluate the safety and effectiveness of the TricValve System with optimal medical therapy (OMT) compared to OMT alone in the treatment of patients with severe tricuspid regurgitation and unsuitable for approved transcatheter therapies. Subjects will be followed at discharge, 1 month, 30 days, 3 months, 6 months 12 months, and annually up to 5 years.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Randomized Cohort: Caval Reflux (CR) grade reduction | 6 months | Reduction in Caval Reflux (CR) assessed by the echocardiography core laboratory. The CR will be assessed using the 3-grade scale: Grade 1 (no reflux, reflux extending for less than 1 cm below the diaphragm), Grade 2 ( reflux extending for less than 3 cm), Grade 3 (reflux of 3 cm or more). Lower grades of CR are better. |
| Randomized Cohort: Hierarchical composite endpoint including: Kansas City Cardiomyopathy Questionnaire (KCCQ) improvement, New York Heart Association (NYHA) functional class improvement, and 6-minute walk test distance improvement | 6 months | Comparison of clinical outcomes using a single hierarchical analysis. Treatment effect will be summarized using Win Ratio statistics, where a value greater than 1 indicates improved outcomes in the experimental group compared with the comparator arm. |
| Randomized Cohort: Rate of Major Adverse Events (MAE) | 30 days | Rate of Major Adverse Events (MAE) in experimental arm (TricValve + OMT) |
| Randomized Cohort: Hierarchical composite endpoint: all-cause mortality, RVAD implantation or heart transplant, tricuspid valve surgery or percutaneous tricuspid intervention, heart failure hospitalizations, KCCQ improvement, NYHA functional class improv | 1 year | Comparison of clinical outcomes using a single hierarchical analysis. Treatment effect will be summarized using Win Ratio statistics, where a value greater than 1 indicates improved outcomes in the experimental group compared with the comparator arm. |
