About this study
Study to evaluate the feasibility, safety and performance of the HighLife trans-septal Transcatheter Mitral Valve in patients with moderate-severe and severe mitral regurgitation who are at high risk for surgical treatment.
Read the 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.

What is being measured
The primary outcome is the main question the study is designed to answer.
Freedom of major adverse events
including:
- All-cause mortality
- Myocardial infarction or coronary ischemia requiring PCI or CABG
- Major stroke
- Life-threatening bleeding (MVARC scale)
- Major access and vascular complications
- Stage 2 or 3 acute kidney injury (includes dialysis)
- Any valve-related dysfunction, migration, thrombosis, or other complication requiring surgery or repeat intervention
- Severe hypotension, heart failure or respiratory failure requiring intravenous pressors or invasive or mechanical heart failure treatments such as ultrafiltration or hemodynamic assist devices, including intra-aortic balloon pumps or left ventricular or biventricular assist devices, or prolonged intubation for ≥ 48H
Measured: at 30 days post procedure
Continued intended performance of the HighLife™ bioprosthesis
defined as the reduction of mitral regurgitation (MR) to either optimal (0+ to trace) or acceptable (reduced by at least 1 grade from baseline with no more than 2+ MR) without significant mitral stenosis (post-procedure EOA ≥ 1.5 cm2 with a transmitral gradient < 5mmHg) and with no greater than mild (1+) paravalvular MR (and without associated hemolysis)
Measured: at 30 days post procedure
Secondary outcomes (1)
Technical success
defined as alive patient at exit from procedure room, with all of the following:
- Successful access, delivery and retrieval of the HighLife delivery systems
- Deployment and correct positioning of the HighLife bioprosthesis
- Freedom of additional emergency surgery or re-intervention related to the device or access procedure
Measured: immediately after procedure
