Evaluating the Risk of Cognitive Impairment After Surgical and Transcatheter Aortic Valve Replacement (CAVIAR)

March 22, 2018 updated by: Santiago Garcia, Minnesota Veterans Medical Research and Education Foundation

Proposal for Collection of Patient Data to Aid in Design of an Observational Study (i.e. Preparatory to Research) Evaluating Risk of Cognitive Impairment After Surgical and Transcatheter Valve Replacement.

The investigators are conducting a pilot study to compare cognitive outcomes among Veterans with severe aortic valve stenosis who are scheduled to undergo either aortic valve replacement.

Study Overview

Detailed Description

The investigators are conducting a pilot study to compare cognitive outcomes in up to 60 Veterans with severe aortic valve stenosis who are scheduled to undergo either transcatheter aortic valve replacement (TAVR) or surgical aortic valve replacement (SAVR) at the Minneapolis VA Health Care System. Participants will be administered a short battery of cognitive tests before and three months after TAVR or SAVR over/up to a two year study period.
