Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 30 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Safety and Performance Study of the NeoChord Suturing Device in Subjects With Degenerative Mitral Valve Disease; Diagnosed With Severe Mitral Regurgitation
Study Start Date : October 2009
Actual Primary Completion Date : October 2012
Actual Study Completion Date : August 2014

Arm Intervention/treatment
Experimental: Implanting ePTFE sutures
Implanting ePTFE sutures as artificial neochordae using the NeoChord DS1000 Artificial Chordae Delivery System
Device: NeoChord DS1000 Artificial Chordae Delivery System

Primary Outcome Measures :
  1. Procedural Success [ Time Frame: 30 days ]
    The placement of at least one neochord using the DS1000 System AND a reduction in mitral regurgitation <= 2+ at the time of the procedure AND maintained MR reduction of <= 2+ at 30 days

Secondary Outcome Measures :
  1. Procedural Safety [ Time Frame: 30 days ]
    the rate of Major Adverse Events (MAE) defined as a combined endpoint of: death, MI, reoperation for failed surgical repair, non-elective cardiovascular surgery to treat an adverse event, procedural ventilation > 48 hours, procedure-related transfusion of > 2 units blood product, stroke, renal failure, deep wound infection, new onset of permanent AF, and septicemia, through 30 days.
