Why the study?
Does transfemoral aortic valve implantation increase the incidence of silent cerebral ischemia compared to open surgical aortic valve replacement?
Does transfemoral aortic valve implantation increase the incidence of silent cerebral ischemia compared to open surgical aortic valve replacement?
TAVI is associated with a higher frequency of clinically silent cerebral ischemic lesions on MRI compared to surgical aortic valve replacement, although these lesions are smaller and not associated with apparent neurological deficits at 3 months.
No takes yet. Share an insight, caveat, or question.
TAVI was associated with more frequent but smaller silent lesions than surgery without deficits; leaves open long-term cognitive impact and valve selection.
Kahlert et al. (2010) studied this question.
