After analyzing outcomes of more than 6,200 transcatheter aortic valve replacements performed at 22 Michigan hospitals between 2016 and mid-2019, a Michigan Medicine study suggests that hospitals without the highest stroke care designation may be missing strokes that occur after a common heart valve replacement procedure. The findings also revealed that comprehensive stroke centers reported significantly greater stroke rates up to 30 days after TAVR, a minimally invasive procedure to replace a thickened aortic valve with an artificial one, 2.21 times higher than hospitals without the designation.
