Summary of studies utilizing DW-MRI to view cerebral ischemia and assessed global cognition using the MMSE.

= number, TAVI = transcatheter aortic valve implantation, MMSE = mini-mental status examination, DW-MRI = diffusion weighted magnetic resonance imaging, ES = Edwards-SAPIEN, and MCV = Medtronic CoreValve.
aOnly 56 patients were able to undergo postprocedural imaging.
