Cerebral Embolic Protection Devices: Current State of the Art

Transcatheter aortic valve replacement (TAVR) has become a first-line treatment for severe stenosis with intermediate to high-risk population its use increasingly expanding into younger and low-risk cohorts as well. Cerebrovascular events are one of the most serious consequential complications TAVR, which increase morbidity mortality. The probable origin such neurological is embolic in nature majority occur acute phase after TAVR when frequent. Cerebral protection devices have been designed capture or deflect these emboli, reducing risk peri-procedural ischaemic events. They also carry potential diminish burden new silent ischemic lesions during TAVR. Our review explores different types device systems, their rationale, established clinical data.
