The MitraClip® EXPAND Study of the Next Generation of MitraClip® Devices
Study Details
Study Description
Brief Summary
The MitraClip EXPAND Study (A Contemporary, Prospective Study Evaluating Real-world Experience of Performance and Safety for the Next Generation of MitraClip Devices) is designed to confirm the safety and performance of the MitraClip NTR System and MitraClip XTR System.

Detailed Description
The data collected in this study will be used to evaluate device outcomes and characterize trends in patient selection for MitraClip therapy in contemporary real-world use. Moreover, the data will be assessed to identify patient or mitral valve anatomical characteristics that may be most appropriate for these next generation devices.
The MitraClip EXPAND Study will be conducted on commercial MitraClip NTR System and MitraClip XTR System that have received CE Mark and/or FDA approval as required.
Up to 1,000 subjects at a maximum of 60 sites in Europe and the US were initially planned to enroll in the MitraClip EXPAND Study.

Outcome Measures
Primary Outcome Measures
- Safety Measure: Number of Participants With Major Adverse Events (MAE) [At 30 Days]
MAE was defined as a composite of all-cause Death, Myocardial Infarction, Stroke, or non-elective Cardiovascular (CV) surgery for device related complications (CEC adjudicated).
- Performance Measure: Number of Participants With Mitral Regurgitation (MR) Reduction to ≤2+ [At 30 days]
The performance was measured by Mitral Regurgitation (MR) Reduction to ≤2+ at 30-day visits.
Eligibility Criteria
Criteria
Inclusion Criteria:
