This study looks at the Trisol system, which is a new way to help people with a heart problem called tricuspid regurgitation (TR). TR happens when the heart's tricuspid valve doesn’t close tightly, allowing blood to flow backward. The study aims to understand how safe the Trisol system is and how well it works. It’s a prospective, single-arm, open-label, multi-center study, meaning everyone knows what treatment is given and there’s only one group of participants.

**To join the study:**

• You must be over 18 and have a moderate or serious TR problem.
• You should be at high risk for regular tricuspid valve surgery but suitable for the new Trisol system.
• You should not have had certain recent heart problems or be dealing with serious infections.

**Key Points:**

• Participants must be able to attend all follow-up visits and comply with study requirements.
• The study may involve multiple visits to the hospital for assessments and procedures.
• Participants will receive the new Trisol treatment, which could offer benefits over traditional surgery.
