CE Mark Study for the Harpoon Medical Device (TRACER)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02768870
Recruitment Status : Active, not recruiting

Brief Summary:
The purpose of this study is to evaluate the safety and performance of the Harpoon Medical device. It is anticipated, that the Harpoon Medical device will provide advantages over current surgical interventions including: 1) a small minimally invasive incision, 2) no sternotomy, 3) no cardiopulmonary bypass, 4) no aortic manipulation, 5) a direct path to the valve plane, 6) performed on a beating heart, 7) real-time TOE-guided chordal length adjustment and 8) less complicated procedure that is teachable and adoptable.

Condition or disease Intervention/treatment Phase
Mitral Valve Regurgitation Mitral Valve Prolapse Mitral Valve Insufficiency Device: Harpoon Artificial ePTFE Chords Not Applicable

Detailed Description:
The device is designed to reduce the degree of mitral regurgitation by delivering and anchoring artificial chordae tendineae to the affected mitral valve leaflet(s) in a beating heart.

Arm Intervention/treatment
Experimental: Harpoon Medical Device
This is a prospective, single arm, nonrandomised, multi-center EU study to demonstrate the performance and safety of the Harpoon Medical device in patients with degenerative MR.
Device: Harpoon Artificial ePTFE Chords
It is anticipated that use of the Harpoon device could achieve similar outcomes to open cardiac surgery while decreasing the invasiveness of mitral valve repair.

Primary Outcome Measures :
  1. Procedural success during the first 30 days [ Time Frame: 30 days ]
    To demonstrate that the Harpoon Medical device performs as designed and has the ability to successfully implant one or more ePTFE chordae tendineae on the mitral valve via a small left thoracotomy on the beating heart and reduce mitral regurgitation from "severe" to less than or equal to "moderate" at the conclusion of the procedure and at 30 days post-procedure.

  2. Freedom from SAE's during the first 30 days [ Time Frame: 30 days ]
    Procedure freedom from Serious Adverse Events (SAEs) during the ePTFE implantation procedure, at discharge, and at 30 days follow-up shall be tracked and recorded. Rates are expected to be not significantly worse than conventional mitral valve surgery.

Secondary Outcome Measures :
  1. Long Term Procedural Success [ Time Frame: 6 months, 12 months, 18 months, 24 months, 30 months, and 36 months ]
    Severity of mitral regurgitation at 6 months, 12 months, 18 months, 24 months, 30 months and 36 months follow-up shall be tracked and recorded.

  2. Freedom from SAE's post implant > 30 days [ Time Frame: 6 months, 12 months, 18 months, 24 months, 30 months, and 36 months ]
    Freedom from Serious Adverse Events (SAEs) at 6 months, 12 months, 18 months, 24 months, 30 months and 36 months follow-up shall be tracked and recorded.
