Primary Outcome Measures
NameTimeMethod
- freedom from all-cause mortality, disabling stroke and life- threaten-ing bleeding at 30 days post-implant.<br>- procedure success at 30 days post-treatment, as measured by: Tech-nical success with reduction of MR to less than or equal to mild and the absence of major device or procedure-related SAEs.<br>
Secondary Outcome Measures
NameTimeMethod
- Technical success defined as survival and exit from the operating room (OR) with successful implantation of 3 or more ePTFE chords.<br> - Freedom from major device or procedure-related serious adverse event (SAE) at 30 days, 1 year and 2 years post-implant.<br> - Freedom from ePTFE chord rupture as reported by echo core lab at 1 year and 2 years post-implant.<br> - Freedom from reoperation or re-intervention due to ePTFE chord rupture at 1 year and 2 years post-implant.<br> - Freedom from reoperation or reintervention on the mitral valve annually through 5 years post-implant<br> - Freedom from >/= moderate MR annually through 5 years post-implant<br> - Functional improvement from baseline NYHA Functional Classification at 1 year and 2 years post-implant<br> - Quality of Life (change from Baseline to 1 and 6 months)<br> - 6 minute walk test (change from Baseline to 1 and 6 months) <br>
