Multicentre Study of Percutaneous Mitral Valve Repair MitraClip Device in Patients With Severe Secondary Mitral Regurgitation

Phase 3
Conditions
Cardiovascular Diseases
Interventions
Device: Percutaneous MitraClip Device Implantation
Other: control
Registration Number
NCT01920698
Lead Sponsor
Hospices Civils de Lyon
Brief Summary

The objective of this trial is to compare the safety, the efficacy and the cost-effectiveness of 2 therapeutic strategies (optimal standard of care therapy alone versus percutaneous MitraClip procedure and optimal standard of care therapy) in patients with severe secondary mitral regurgitation.

This trial is a French, multicenter and randomized trial. Patients enrolled will be clinically followed for 2 years (phone call at 1 month, clinical visit at 6 months, 12 months and 24 months).

Secondary Outcome Measures
NameTimeMethod
Change in Quality of Life score as measured by the European Quality of Life-5 Dimensions instrument.6 months and 12 months
Change in echocardiographic evaluation between baseline at 6, 12 and 24 months.6 months, 12 months and 24 months
Serious Adverse Events30 days, 6 months, 12 months and 24 months.

Any serious adverse events cardiovascular or not occurring within each group.

Change in functional evaluation12 months
Cost-effectiveness of each strategy at 12 months12 months

Cost-effectiveness of each therapeutic strategy will be assessed by the evaluation of medical costs linked to the pathology (hospitalizations, consultations, and external medical costs (biology, radiology, medications) and compared in the 2 groups during the first 12 months of follow up.

All-cause mortality, cardiac mortality30 days, 6 months, 12 months, and 24 months.
Survival with no major cardiovascular events30 days, 6 months, 12 months, and 24 months.
Change in biomarkers (BNP levels, creatinine) at 6 months and 12 months6 months and 12 months
