Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Severe Tricuspid Regurgitation Device: TricValve® System Not Applicable

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 with the aim of CE certification is designed to investigate the safety and performance for at least 30 days and up to 5 years.

Primary Purpose: Treatment
Official Title: TRICUS STUDY EURO - Safety and Efficacy of the TricValve® Transcatheter Bicaval Valves System in the Superior and Inferior Vena Cava in Patients With Severe Tricuspid Regurgitation
Actual Study Start Date : December 9, 2019
Estimated Primary Completion Date : May 2021
Estimated Study Completion Date : March 2025

Arm Intervention/treatment
Experimental: TricValve® System Single-Arm
Two self-expanding biological valves for implantation into the inferior and superior vena cava.
Device: TricValve® System
The TricValve® Delivery System (catheter) with already pre-mounted biological heart valve 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 released at the implantation site and positions itself as per the anatomy - self expanding frame.




Primary Outcome Measures :
  1. Percentage of participants with major adverse events [ Time Frame: 30 days ]
    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)

  2. Kansas City Cardiomyopathy Questionnaire (KCCQ) [ Time Frame: 3 months ]
    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.)


Secondary Outcome Measures :
  1. Percentage of participants with major adverse events [ Time Frame: up to 6 months, up to 5 years ]
    The percentage of participants with major adverse events

  2. Successful implantation [ Time Frame: Up to Discharge (≤ 10 days post index procedure) ]
    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.

  3. Unrestricted movement of cusps [ Time Frame: Up to 30 days, up to 6 months, up to 5 years ]
    The percentage of medical devices with unrestricted movement of cusps after implantation as assessed with echocardiography (nominal)

  4. Cusp insufficiency [ Time Frame: Up to 30 days, up to 6 months, up to 5 years ]
    The change of the degree of cusp insufficiency as assessed with echocardiography (ordinal) from a higher to a lower value

  5. Device success [ Time Frame: Up to 30 days, up to 6 months, up to 5 years ]
    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®.

  6. NYHA functional class [ Time Frame: Up to 30 days, up to 5 years ]
    Change of New York Heart Association (NYHA) functional class from III or IV to a lower one

  7. 6 Minute Walk Test [ Time Frame: Up to 30 days, up to 6 months, up to 5 years ]
    Improvement in distance (m) in the 6 Minute Walk Test

  8. Kansas City Cardiomyopathy Questionnaire (KCCQ) [ Time Frame: Up to 6 months, up to 5 years ]
    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.)
