The BHF PROTECT-TAVI randomized trial found no cognitive benefit from using cerebral embolic protection devices during transcatheter aortic valve implantation, despite their theoretical role in mitigating embolic brain injury.

The BHF PROTECT-TAVI randomized trial reveals that cerebral embolic protection (CEP) devices do not prevent cognitive decline following transcatheter aortic valve implantation (TAVI), challenging assumptions about their neuroprotective benefits.
