Brief Title
An Early Feasibility Study of the HighLife 28mm Trans-Septal Transcatheter Mitral Valve Replacement System
Detailed Description
Protocol Title:
An Early Feasibility Study of the HighLife 28mm Transcatheter Trans-Septal Mitral Valve Replacement System
Protocol # HL-2019-01, ver. 5.0
Phase: United States Early Feasibility Study
Investigational Devices:
The HighLife 28mm Trans-Septal Mitral Valve and its delivery systems. These devices compose the HighLife Trans-septal Mitral Valve Replacement (TSMVR) System.
* Size 28 mm TMV (CLARITY valve)
* Size 28 mm TMV-L (CLARITY large annulus valve/ LAV)
Intended Use: The HighLife TSMVR system is intended for the trans-septal access percutaneous mitral valve replacement in patients suffering from symptomatic moderate-severe or severe mitral regurgitation (MR) due to primary (degenerative) or secondary (functional) abnormality of the mitral valve.
Device Description:
The HighLife TSMVR system is composed of a Trans-Septal (Mitral Valve (TSMV), a sub-annular implant (SAI), and their delivery systems and accessories. The TMV is a 28 mm mitral bioprosthesis made of a self-expanding Nitinol frame covered with polyester graft and supporting bovine pericardium leaflets. The bioprosthesis is used in conjunction with the Sub-Annular Implant (SAI), comprising a ring (made of polycarbonate urethane (PCU), nitinol, gold markers and polyester (Dacron) to be placed around the mitral valve apparatus to stabilize the position of the mitral valve implant.
Design: A single arm, prospective, multicenter, non-randomized and open-labelled study.
Purpose: The purpose of the study is to evaluate the feasibility, safety and performance of the HighLife 28mm Trans-septal Mitral Valve Replacement (TSMVR) system in NYHA Class ≥ II-IV patients with moderate-severe or severe mitral regurgitation who are at high risk for surgical treatment or deemed more appropriate to receive transcatheter mitral valve replacement than to receive conventional mitral valve surgery according to the local multidisciplinary Heart Team.
Objectives: Primary objectives are to evaluate the feasibility, safety and performance of the HighLife 28mm TSMVR system at 30 days. Secondary objectives are to evaluate long term safety and performance of the HighLife TSMVR system.
