About this study

Official title: TRICUS STUDY - Safety and Efficacy of the TricValve® Transcatheter Bicaval Valves System in the Superior and Inferior Vena Cava in Patients With Severe Tricuspid Regurgitation.

The TricValve® Transcatheter Bicaval Valves System is indicated for relief of tricuspid insufficiency in patients with symptomatic heart disease who are judged by a heart team, including a cardiac surgeon, to be at extreme risk or inoperable for open surgical therapy.

Read the detailed description

TricValve® Transcatheter Bicaval Valves is a system of two self-expanding biological valves for the treatment of patients with hemodynamically relevant tricuspid insufficiency and caval reflux. The prostheses are implanted percutaneously into the inferior and superior vena cava without disturbing the native tricuspid valve. It is especially intended for use for patients at extreme risk or who are inoperable for open surgical therapy.

Pre-Clinical and Clinical preliminary studies have shown an acceptable safety and performance profile of the TricValve® Transcatheter Bicaval Valves System. Given that the medical device is a potential long-term treatment for patients with tricuspid insufficiency, clinical data for long-term treatment periods is necessary. Thus, the current study is designed to investigate the safety and performance for at least 30 days and up to 6 months.

The study has been approved by the Kaunas Regional Biomedical Research Ethics Committee.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • TricValve® SystemDevice

    The TricValve® Delivery System is inserted from the femoral vein to access the inferior vena cava (IVC) and superior vena cava (SVC) of the heart under fluoroscopy guidance. The appropriately sized TricValve® is unsheathed at the implantation site and positions itself as per the anatomy - self expanding frame.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of participants with major adverse events

    The percentage of participants with major adverse events (death, myocardial infarction, cardiac tamponade, cardiac surgery for failed TricValve® implantation, stroke. Major bleeding according to Valve Academic Research Consortium (VARC) criteria)

    Measured: 30 days

  2. Change of New York Heart Association (NYHA) functional class

    Change of New York Heart Association (NYHA) functional class from III or IV to a lower one

    Measured: 6 months

Secondary outcomes (7)

  1. Successful implantation

    The percentage of surviving participants with successful access, delivery and retrieval of the device delivery system, and deployment and correct positioning of the intended device(s), and no need for additional unplanned or emergency surgery or re-intervention related to the device or access procedure.

    Measured: Up to Discharge (≤ 10 days post index procedure)

  2. Unrestricted movement of cusps

    The percentage of medical devices with unrestricted movement of cusps after implantation as assessed with echocardiography (nominal)

    Measured: Up to 30 days, up to 6 months

  3. Cusp insufficiency

    The change of the degree of cusp insufficiency as assessed with echocardiography (ordinal) from a higher to a lower value

    Measured: Up to 30 days, up to 6 months

  4. Device success

    Device success as measured by number of patients who are alive with intended device in place with no additional surgical or interventional procedures related to the TricValve®.

    Measured: Up to 30 days, up to 6 months

  5. NYHA functional class

    Number of Patients with improvement of NYHA functional class

    Measured: Up to 30 days

  6. 6 Minute Walk Test

    Improvement in distance (m) in the 6 Minute Walk Test

    Measured: Up to 30 days, up to 6 months

  7. Kansas City Cardiomyopathy Questionnaire (KCCQ)

    Number of Patients with improvement in quality of life as assessed by Kansas City Cardiomyopathy Questionnaire (KCCQ, 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. Range of 0-100, in which higher scores reflect better health status.)

    Measured: Up to 30 days, up to 6 months

Questions about this trial

What is this clinical trial studying?

A study testing TricValve® System in people with Severe Tricuspid Regurgitation, run by P+F Products + Features GmbH at 1 site in Lithuania.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 19 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 20 Apr 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Lithuania. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percentage of participants with major adverse events (time frame: 30 days). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03723239, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Apr 2022; AzTrials last refreshed its copy on 8 Nov 2026.
