Patients With Severe TrIcuspid Regurgitation After triCvALve System Implantation

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.

Eligibility

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)
4. The subjects must have severe, tricuspid regurgitation leading to New York Heart Association (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 informed consent 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:

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. Life expectancy 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 platelet 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. Contraindication or known allergy to device's components, anti-coagulation therapy with vitamin K antagonists or contrast media that cannot be adequately pre-treated
12. Patients unsuitable for implantation because of thrombosis of the lower venous system or vena cava filter
13. Evidence of an acute myocardial infarction (AMI) ≤ 1 month (30 days)
14. Liver cirrhosis Child C
15. Female patient of child-bearing potential
16. Currently participating in another study of an investigational drug or device that would directly impact the treatment or outcome of the current study
