Cerebral embolic protection during transcatheter aortic valve replacement

After more than 20 years of development, the complications of transcatheter aortic valve replacement (TAVR) have been significantly reduced, but the incidence of stroke has not been significantly reduced. In recent years, a variety of cerebral embolic protection device (CEPD) have been applied in clinical practice, but their effectiveness is still controversial due to the lack of high ⁃ quality clinical evidence. This article reviews progress on the risk factors for stroke and the characteristics of intraoperative CEPD in TAVR, so as to provide reference for the selection of TAVR cases and the formulation of cerebral embolic protection strategies.
