Predictors of Postoperative Delirium After Transcatheter Aortic Valve Implantation

Incidence and Risk Factors of Acute Postoperative Confusion State After Trans-catheter Aortic Valve Implantation (TAVI)

Patients undergoing transcatheter aortic valve implantation (TAVI) have distinctive characteristics: they are old, frail, with several co-morbidities and take multiple medications. Hemodynamic instability, cerebral embolism, sedation, general anesthesia and hospitalization in intensive care expose those patients to postprocedural delirium.

Acute neurocognitive dysfunctions are associated with adverse outcomes in these population.

The objective of this study is to determine the incidence of delirium and neurocognitive disorders in elderly patients after TAVI.

Inclusion Criteria:

• Age 65>years
• Patients undergoing transcatheter aortic valve implantation
• Patients have given informed consent for participation at the study

Exclusion Criteria:

• Patient suffering from delirium (CAM diagnosis) at recruitment
• Inability to understand the national languages
• Emergency procedures
