One of the most important complications of transcatheter aortic valve implantation (TAVI) is represented by cerebrovascular events, often associated with a significant increase of postprocedural mortality and disability. This chapter describes incidence, predictors and possible preventive strategies of cerebrovascular events during TAVI. It is well known that TAVI is associated with an inevitable risk of neurological complications and their incidence has been studied and compared to the one related to surgical aortic valve replacement (SAVR) in many studies. In a study enrolling intermediate‐risk populations, stroke incidence after TAVI was inferior to the one after SAVR. Postprocedural stroke incidence follows a bimodal distribution. Cerebral debris embolization during TAVI is frequent and, if searched by neuroimaging modalities, almost constant. However, initial study data have shown that it is easily preventable with the use of embolic protection devices.

Abstract
One of the most important complications of transcatheter aortic valve implantation (TAVI) is represented by cerebrovascular events, often associated with a significant increase of postprocedural mortality and disability. This chapter describes incidence, predictors and possible preventive strategies of cerebrovascular events during TAVI. It is well known that TAVI is associated with an inevitable risk of neurological complications and their incidence has been studied and compared to the one related to surgical aortic valve replacement (SAVR) in many studies. In a study enrolling intermediate‐risk populations, stroke incidence after TAVI was inferior to the one after SAVR. Postprocedural stroke incidence follows a bimodal distribution. Cerebral debris embolization during TAVI is frequent and, if searched by neuroimaging modalities, almost constant. However, initial study data have shown that it is easily preventable with the use of embolic protection devices.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
