Cerebral emboli are a common risk of transcatheter aortic valve implantation (TAVI). In a clinical trial involving 100 patients with severe aortic stenosis who were randomly assigned to undergo TAVI with or without a cerebral embolism protection (filter) device, Haussig and colleagues found that use of the protection device reduced the frequency of ischemic lesions. In an Editorial, Messé and Mack discuss interventions to improve cerebral safety of high-risk cardiovascular procedures.
