Incidence, risk factors and prognostic impact of cerebrovascular events after transcatheter aortic valve implantation

Key Result

Cerebrovascular events after transcatheter aortic valve implantation were linked to double the odds of 1-year all-cause mortality.

Key Points

• To assess the incidence and risk factors of cerebrovascular events after transcatheter aortic valve implantation (TAVI) and their effect on mortality.
• Analyzed clinical data from patients who underwent TAVI.
• Identified risk factors associated with cerebrovascular events.
• Evaluated the impact of these events on 1-year survival rates.
• Cerebrovascular events post-TAVI were linked to double the odds of all-cause mortality within one year.
• Key risk factors included the use of self-expandable valves, new-onset atrial fibrillation, diabetes, and sternotomy conversions.
• Smaller aortic valve area was also associated with higher risk of cerebrovascular events.
