The risk and extent of neurologic events are equivalent for high-risk patients treated with transcatheter or surgical aortic valve replacement

Neurologic outcomes were evaluated in a randomized trial of TAVR or surgical aortic valve replacement (SAVR) for severe AS (750 pts).   Stroke occurred about 50% more often in SAVR than TAVR pts at all follow-up time periods, but the differences were not statisticalyl significant.  Cognitive changes after stroke were similar between the two groups.
