Brief Summary:
The objective of this early feasibility study is to gain early clinical insight into the performance of the Intrepid transcatheter tricuspid valve replacement (TTVR) system intended for transfemoral access to deliver a self-expanding bioprosthetic valve within the tricuspid valve.

Condition or disease Intervention/treatment Phase
Tricuspid Regurgitation Device: Intrepid™ TTVR System Not Applicable

Detailed Description:
Multi-center, prospective, non-randomized, investigational, and pre-market.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 15 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: The Early Feasibility Study of the Transcatheter Tricuspid Valve Replacement System Transfemoral System
Actual Study Start Date : October 20, 2020
Estimated Primary Completion Date : April 28, 2023
Estimated Study Completion Date : November 15, 2026

Arm Intervention/treatment
Experimental: Primary Cohort
Device: Intrepid TTVR System
Device: Intrepid™ TTVR System
Device: Intrepid™ TTVR System

Primary Outcome Measures :
  1. Rate of implant or delivery related serious adverse events [ Time Frame: Through 30 days post-procedure ]
    Rate of implant or delivery related serious adverse events

Secondary Outcome Measures :
  1. Successful access, delivery of implant, and retrieval of the delivery system assessed by definitions per Mitral Valve Academic Research Consortium (MVARC) [ Time Frame: During Procedure ]
    For procedural success to be present, device success must have been achieved without major clinical complications as detailed per clinical trial design principles and endpoint definitions for transcatheter mitral valve repair and replacement (part 2: endpoint definitions)

  2. Change in TR Grade from baseline [ Time Frame: Through 30 days post-procedure ]
    Change in TR Grade from baseline

  3. Rate of no significant TV stenosis [ Time Frame: Through 30 days post-procedure ]
    Rate of no significant TV stenosis

  4. Change in NYHA Class from baseline [ Time Frame: Through 30 days post-procedure ]
    Change in NYHA Class from baseline

Layout table for eligibility information
Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Heart Team agrees that patient is deemed symptomatic despite medical therapy (including obligatory diuretic) and a candidate for bioprosthetic tricuspid valve replacement
  • Subject is at an intermediate or greater estimated risk of mortality with tricuspid valve surgery as determined by the local Heart Team
  • Subjects with severe symptomatic primary and / or secondary tricuspid regurgitation determined by the Echocardiography Core Lab assessment of a qualifying transthoracic echocardiogram (TTE) and transesophageal echocardiogram (TEE)
  • New York Heart Association (NYHA) Function Class II or greater
  • Subject anatomically suitable for the Intrepid TTVR delivery system including transfemoral access
  • Subject and the treating physician agree that the subject will return for all required post-procedure follow-up visits
  • Subject meets the legal minimum age to provide informed consent based on local regulatory requirements

Exclusion Criteria:

  • Estimated life expectancy of less than 24 months due to associated non-cardiac co-morbid conditions
  • Anatomic contraindications for Intrepid™ TTVR (e.g., annular dimensions)
  • Evidence of intracardiac mass, inferior vena cava, or femoral venous mass or thrombus
  • Implanted with venous stents (iliac and/or femoral) or inferior vena cava (IVC) filter or congenital abnormalities of the IVC that would preclude ability for transfemoral access of delivery system
  • Echocardiographic evidence of severe right ventricular dysfunction
  • Left ventricular ejection fraction (LVEF) <30 as measured by resting echocardiogram within 30 days of the Index Procedure
  • Need for emergent or urgent surgery
  • Untreated clinically significant coronary artery disease requiring revascularization
  • Carcinoid tricuspid regurgitation
