TTVR Early Feasibility Study
What this study is about
The objective of this early feasibility study is to gain early clinical insight into the performance of the Intrepid transcatheter tricuspid valve replacement (TTVR) system intended for transfemoral access to deliver a self-expanding bioprosthetic valve within the tricuspid valve.

Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Heart Team agrees that patient is deemed symptomatic despite medical therapy (including obligatory diuretic) and a candidate for bioprosthetic tricuspid valve replacement
- Subject is at an intermediate or greater estimated risk of mortality with tricuspid valve surgery as determined by the local Heart Team
- Subjects with severe symptomatic primary and / or secondary tricuspid regurgitation determined by the Echocardiography Core Lab assessment of a qualifying transthoracic echocardiogram (TTE) and transesophageal echocardiogram (TEE)
- New York Heart Association (NYHA) Function Class II or greater
- Subject anatomically suitable for the Intrepid TTVR delivery system including transfemoral access
- Subject and the treating physician agree that the subject will return for all required post-procedure follow-up visits
- Subject meets the legal minimum age to provide informed consent based on local regulatory requirements
Exclusion criteria
- Estimated life expectancy of less than 24 months due to associated non-cardiac co-morbid conditions
- Anatomic contraindications for Intrepid™ TTVR (e.g., annular dimensions)
- Evidence of intracardiac mass, inferior vena cava, or femoral venous mass or thrombus
- Implanted with venous stents (iliac and/or femoral) or inferior vena cava (IVC) filter or congenital abnormalities of the IVC that would preclude ability for transfemoral access of delivery system
- Echocardiographic evidence of severe right ventricular dysfunction
- Left ventricular ejection fraction (LVEF) \<30 as measured by resting echocardiogram within 30 days of the Index Procedure
- Need for emergent or urgent surgery
- Untreated clinically significant coronary artery disease requiring revascularization
- Carcinoid tricuspid regurgitation

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
