The purpose of this study is to demonstrate the safety and performance of the NeoChord DS1000 Artificial Chordae Delivery System in implanting ePTFE sutures(s) as artificial neochordae in patients with mitral regurgitation.

Condition Intervention
Mitral Valve Regurgitation Device: NeoChord DS1000 Artificial Chordae Delivery System

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: 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

Further study details as provided by NeoChord:

Primary Outcome Measures:
  • 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:
  • 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.

Enrollment: 30
Study Start Date: October 2009
Study Completion Date: August 2014
Primary Completion Date: October 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
