Details and patient eligibility

About

The study is an early feasibility study to measure individual patient clinical outcomes and effectiveness, evaluate the safety and function of the DUO Transcatheter Tricuspid Coaptation Valve System (DUO System).

Full description

Multi-center, prospective, non-randomized, investigational, and pre-market. Data collected in this clinical study will include safety and function of the investigational system as well as up to 5 year clinical outcomes.

Enrollment

15 estimated patients

Sex

All

Ages

18+ years old

Volunteers

No Healthy Volunteers

Inclusion criteria

  1. Presence of severe or greater tricuspid regurgitation as determined by the Echo Core Lab.
  2. Patient is symptomatic despite medical therapy.
  3. The local Site Heart Team determines the Patient is appropriate for transcatheter valve intervention.
  4. The Patient's anatomy is suitable in the judgment of the Patient Selection Committee.
  5. Age ≥18 years
  6. The Patient has been informed of the nature of the study and agrees to its provisions and has provided written Informed Consent.

Exclusion criteria

  1. Patient is currently participating in another clinical investigation that could affect the outcome of this trial.
  2. Any previous tricuspid valve intervention that would interfere with the placement of the investigational device.
  3. Moderate or greater tricuspid valve stenosis.
  4. Severe aortic, mitral and/or pulmonic valve stenosis and/or regurgitation
  5. Pacemaker or implantable cardioverter-defibrillator (ICD) leads that would prevent appropriate placement of the investigational device.
  6. Need for concomitant surgical or interventional procedure, known at the time of screening (e.g., CABG, Atrial Septal Defect (ASD) repair).
  7. Ejection Fraction (EF) <25%
  8. Echocardiographic evidence of unstable intracardiac mass, thrombus or vegetation
  9. Patient has Systolic Pulmonary Pressure (sPAP) >60 mm Hg
  10. Severe hemodynamic instability: cardiogenic shock or the need for inotropic support or Intra-Aortic Balloon Pump (IABP) or other percutaneous ventricular assist devices
  11. Severe respiratory instability with continuous use of home oxygen
  12. Severe right ventricular dysfunction
  13. Untreated clinically significant coronary or carotid artery disease requiring revascularization surgical or interventional PCI.
  14. Stroke or transient ischemic event within 90 days prior to the index procedure
  15. Acute myocardial infarction within 30 days before the index procedure
  16. Renal insufficiency (eGFR <25 ml/min) or currently on chronic dialysis
  17. Active endocarditis within 6 months of the index procedure
  18. Pulmonary embolism or deep vein thrombosis within the last 6 months
  19. Any surgical, interventional, or transcatheter procedure within 30 days prior to the index procedure
  20. Hypertrophic cardiomyopathy, restrictive cardiomyopathy or constrictive pericarditis
  21. Life expectancy <1 year
  22. Active infections requiring current antibiotic therapy
  23. Known severe liver disease
  24. Is on the waiting list for a transplant or has had a prior heart or lung transplant
  25. Known active peptic ulcer or active GI bleed
  26. Unable to take anticoagulant therapy
  27. Any known major coagulation abnormalities, thrombocytopenia, platelets < 50,000/ml or severe anemia Hb <8 g/dl
  28. Known patient is actively abusing drugs
  29. Any known sensitivities or allergies to contrast (that cannot be adequately premedicated) and/or the device materials, including nickel and titanium
  30. Patients who are pregnant or intend to become pregnant
  31. Any condition making it unlikely the Patient will be able to complete all protocol procedures (including compliance with optimal medical therapy and immobility that would prevent completion of 6MWT), follow-up visits, or impact the scientific soundness of the clinical investigation result
