Impact of Cerebral Embolic Protection Devices on the Incidence and Outcomes of Delirium After Transcatheter Aortic Valve Implantation

Postoperative delirium is a well-recognized complication after transcatheter aortic valve implantation (TAVI) that is associated with a significantly increased mortality and prolonged hospitalization stay.1 Ischemic brain injury has been hypothesized to be one of the predominant mechanisms responsible for delirium after TAVI. Brain injury during TAVI involves microinfarctions caused by cerebral embolization of the aortic plaque or valve particles dislodged during the prosthesis deployment.1,2 The role of cerebral embolic protection (CEP) devices has been studied in preventing stroke during TAVI.
