Brief Summary:
The objective of this trial is to assess the safety and effectiveness of the study device in subjects with degenerative mitral valve disease receiving a mitral valve repair without cardiopulmonary bypass (treatment group) when compared to subjects receiving mitral valve repair using standard surgical techniques with cardiopulmonary bypass (control group).

Condition or disease Intervention/treatment Phase
Mitral Valve Insufficiency Device: NeoChord DS1000 Device: Surgical Mitral Valve Repair Not Applicable

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 585 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Randomized Trial of the NeoChord™ DS1000™ System Versus Open Surgical Repair
Actual Study Start Date : November 2016
Estimated Primary Completion Date : July 2020
Estimated Study Completion Date : July 2025

Arm Intervention/treatment
Experimental: Treatment Group
Subjects with degenerative mitral valve insufficiency treated with artificial chordae implanted using the NeoChord DS1000
Device: NeoChord DS1000
Trans-apical, beating heart repair of degenerative mitral valve insufficiency with artificial chordae implanted with the NeoChord DS1000

Active Comparator: Control Group
Subjects with degenerative mitral valve insufficiency treated with standard surgical mitral valve repair
Device: Surgical Mitral Valve Repair
Surgical repair of degenerative mitral valve insufficiency with cardiopulmonary bypass, and annuloplasty ring and some form of leaflet repair or artificial chordae.

Primary Outcome Measures :
  1. Proportion of subjects free of Major Adverse Events (MAEs) in the treatment group when compared to subjects in the control group. [ Time Frame: Post-operative Day (POD) 30 ]
  2. Proportion of subjects free of Grade II, III or IV mitral regurgitation, mitral valve replacement or mitral valve reintervention in the treatment group when compared to subjects in the control group. [ Time Frame: 1 year ]
