Clinical and silent stroke following aortic valve surgery and transcatheter aortic valve implantation. [Review]
Clinical and silent stroke following aortic valve surgery and transcatheter aortic valve implantation. [Review]
Available in print through MWHC library: 2002 - present
Transcatheter aortic valve implantation (TAVI) has been introduced as an alternative to conventional surgery for high-risk patients with aortic stenosis. A recently published randomized clinical trial demonstrated reduction of mortality in high-risk or inoperable patients when compared to medical treatment or balloon aortic valvuloplasty. Despite this evidence of superiority, the rate of TAVI complications is high, and perhaps the most devastating of the nonfatal complications is cerebral injury. This review will compare the incidence of stroke and "silent" cerebral injury after surgical aortic valve replacement and after TAVI and will discuss mechanisms that can lead to cerebral injury during these procedures and subsequently how to prevent this with new protection devices.
