TAVR was associated with a consistently low risk of all-cause mortality or disabling stroke.

One previous study had suggested outcomes may improve in the afternoon, but researchers did not find that to be the case. 

Researchers emphasized that permanent pacemakers are “one of the most feared complications" associated with TAVR. 

TAVR-related stroke, the authors wrote, is a "critically important and potentially preventable source of patient morbidity."

The risk of all-cause mortality, stroke, major bleeding events or permanent pacemaker implantation was similar between the two valves.

Researchers reported "significant improvements" in patients after one year. 

Imaging-based PAD may provide value as a noninvasive alternative to right heart catheterization.
