Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Summary
Brief summary
The primary objective of the MitraClip System Australia and New Zealand (ANZ) Clinical Trial is to gather real-world clinical and health-economic outcome data to support the long-term safety, efficacy and economic value of the MitraClip System in the continuum of therapies for treating MR. Specifically, the following clinical and economic data will be collected: New York Heart Association (NYHA) Functional Class, Six-Minute Walk Test (6MWT) distance, quality of life (QOL) information, echocardiographic measures of left ventricular size and function, and data associated with the index hospitalization, rehospitalizations, concomitant medications and discharge facility to support the MitraClip System economic analysis.
