Adult (>18 years) patients with aortic stenosis in whom TAVI is planned and who perform their pre-TAVI work-up in our centre will be invited to undergo cognitive assessment using the MoCA at the time of their hospitalization for pre-TAVI work-up.

The MoCA will be administered by trained professionals with MoCA certification.
