Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Transcatheter edge-to-edge repair of the mitral valve (M-TEER) is a well-established endovascular treatment option for patients with severe mitral regurgitation who are at high risk for surgery-related complications. However, the procedure carries a risk of clinically overt strokes and imaging-detected brain lesions, which may potentially be mitigated through the use of cerebral protection devices.

This prospective, multi-center, randomized, controlled study aims to assess the efficacy and safety of cerebral protection device, compared to a control group undergoing unprotected M-TEER.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Subjects with indications for M-TEER and who meet study eligibility criteria will be randomized 1:1 to one of two treatment arms: 1) intervention: cerebral protection device with M-TEER or 2) Control: Unprotected M-TEER.

Enrolled subjects will undergo a diffusion weighted magnetic resonance imaging (DW-MRI) at baseline and at 72 hours, to evaluate any new cerebral lesions. Enrolled subjects will be followed for 30 days.

The study aims to address:

* To determine whether the total amounts of new brain lesion assessed by diffusion weighted magnetic resonance images at 72 hours is comparable between the experimental group and the control group.
* To assess the effectiveness and safety of cerebral protection device in the prevention of perioperative cerebrovascular events after M-TEER
* To explore the correlation between the volume/number/location of new brain lesions and changes in neurocognitive function
* To evaluate the histopathological features of the captured fragments and their relevance to clinical features
