- Montreal Cognitive Assessment [ Time Frame: Three Months ]Estimate the means and standard deviations of changes in selected cognitive measures between baseline (pre-TAVR or pre-SAVR) and 3 months post-TAVR or post-SAVR, identify baseline correlates of those changes, and characterize baseline cognitive function and cognitive history of patients who undergo TAVR or SAVR.
- Trail Making [ Time Frame: 3 months ]
