Study summary

International Registry to collect patients with severe TR undergoing TricValve implantation from multiple Italian and European centers, aimed at:

  • Assessing the effect of TricValve implantation on cardiovascular and all-cause mortality, HF rehospitalization, renal function, functional capacity and quality of life.
  • Clarifying the haemodynamic effects of TricValve implantation and investigating their pathophysiological implications.

Study Design

Type of study: Non-profit, multi-center, observational, prospective cohort study (with retrospective inclusion of the first cases performed)

    • Echocardiographic data including Comprehensive 2D and Doppler Transtoracic Echocardiography and Transoesophageal Echocardiography;
    • Anatomical data (Cardiac CT).
  • At the time of procedure we will collect (see eCRF):

    • Procedural data including the occurrence of peri-procedural complications;
    • Haemodynamic data (Right Heart Catheterization).
  • At discharge we will collect (see eCRF):

    • Clinical data regarding clinical status and medications;
    • Biohumoral data (blood and urine chemistry);

    • Peri-procedural data including the occurrence of peri-procedural complications.
  • At 30-day follow-up we will collect (see eCRF):

    • Clinical data regarding medical history, clinical status and medications;
    • Biohumoral data (blood and urine chemistry);
    • Echocardiographic data including comprehensive 2D and Doppler Transtoracic Echocardiography;
  • At 6-month follow-up we will collect (see eCRF):

    • Clinical data regarding medical history, clinical status and medications;
    • Biohumoral data (blood and urine chemistry);
    • Echocardiographic data including comprehensive 2D and Doppler transthoracic echocardiography;
    • Haemodynamic data (Right Heart Catheterization), if clinically indicated.
  • At 1-year follow-up we will collect (see eCRF):

    • Clinical data regarding medical history, clinical status and medications;
    • Biohumoral data (blood and urine chemistry);
    • Echocardiographic data including Comprehensive 2D and Doppler Transtoracic Echocardiography;
    • Haemodynamic data (Right Heart Catheterization), if clinically indicated.

Study population

Patients with severe, massive or torrential tricuspid regurgitation (TR) undergoing TricValve implantation from multiple Italian and European centers

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  1. The subject must be 18 years of age or older
  2. The subject must be a patient with massive or torrential symptomatic tricuspid regurgitation demonstrated by echocardiography with significant backflow in the IVC and/or SVC and with a v-wave ≥ 25 mmHg as demonstrated by right heart catheterization (measured in the IVC and/or SVC 2-4 cm above/ below right atrium (RA) inflow) within 8 weeks prior to the implantation
  3. Suitable for TricValve Transcatheter Bicaval Valves System implantation according to anatomic criteria by computed tomography (CT)inserire la parte retrospettiva ossia i pazienti che già hanno avuto l'impianto
  4. The subjects must have severe, tricuspid regurgitation leading to (NYHA) class III or IV
  5. Distance covered in 6-minute walk test (6MWT) ≥ 60m
  6. Patient/authorized legal guardian understands the nature of the procedure, is willing to comply with associated follow-up evaluations, and provides written Patient/patient's authorized legal guardian is geographically stable (or willing to return for required study follow-up) and understands and is willing to fulfil all of the expected requirements of the clinical protocol

Exclusion criteria

Exclusion Criteria

  1. Known significant intracardiac shunt (e.g. ventricular septal defect) or congenital structural heart disease based on heart team decision
  2. Requirement for other elective cardiac procedures e.g. Percutaneous Coronary Intervention (PCI) or Coronary Artery Bypass Graft (CABG) up to 90 days after the procedure or 30 days before the procedure
  3. Right ventricular failure (TAPSE ≤13 mm)
  4. Systolic pulmonary arterial pressure > 65 mmHg as assessed by Doppler echocardiography
  5. less than one year
  6. Cerebro-vascular event within the past 3 months
  7. History of mitral/tricuspid endocarditis within the last 12 months
  8. Patient has untreated significant left sided valvular heart disease which requires treatment (e.g. mitral regurgitation or stenosis, and aortic regurgitation or stenosis)
  9. Documented primary coagulopathy or disorder, including thrombocytopenia (absolute platelet count \<90k)
  10. Documented evidence of significant renal dysfunction (serum creatinine > 3.0mg/dl) or on any form of dialysis at time of screening within the last 4 weeks
  11. or known allergy to device's components, anti-coagulation therapy with vitamin K antagonists or contrast media that cannot be adequately pre-treated
  12. Evidence of an acute myocardial infarction (AMI) ≤ 1 month (30 days)
  13. Currently participating in another study of an drug or device that would directly impact the treatment or outcome of the current study
Terms in these criteria, in plain language(6)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

NYHA class (heart failure)

The New York Heart Association’s four classes of how much heart failure limits physical activity.

I
No limits: ordinary activity causes no undue tiredness or breathlessness.
II
Slight limits: comfortable at rest, ordinary activity causes symptoms.
III
Marked limits: comfortable at rest, less than ordinary activity causes symptoms.
IV
Symptoms even at rest; any activity makes them worse.

Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
