Which patients are most likely to suffer stroke following TAVR?

11/25/2013 | Star Tribune (Minneapolis-St. Paul, Minn.)

A Minneapolis cardiologist and a California mechanical engineer are working to determine which particles loosened during transcatheter aortic valve replacement are likely to cause a subsequent stroke. Dr. Robert Schwartz of the Minneapolis Heart Institute Foundation and Shawn Shadden of the University of California, Berkeley, used computational fluid dynamics to measure fluid flows, leading them to conclude that particles in the 1-millimeter range are most likely to cause a significant stroke. Schwartz is seeking a grant to validate the initial research, which he says could allow for prediction and prevention of stroke in TAVR patients.
