Cerebral embolic protection systems for transcatheter aortic valve replacement

Abstract

In the recent years, ischemic brain injury related to embolization after transcatheter aortic valve replacement (TAVR) has received increased attention as new embolic protection strategies emerged to protect the brain. Diverse cerebral protection devices have been developed to reduce cerebral embolization during TAVR. These devices work through various mechanisms and are in different stages of clinical translation. This review provides the evidence-based review of peri-procedural stroke prevention during TAVR and summarizes currently available cerebral embolic protection devices.
