Key result
Transcatheter aortic valve implantation in high-risk patients showed 51% overall survival at median 3.7 years, with preserved hemodynamic function and no structural valvular deterioration.
Why the study?
Does transcatheter aortic valve implantation provide durable valve function and survival in high-risk patients declined for surgery?
Population
89 consecutive high-risk patients declined as surgical candidates because of comorbidities
Design
Cohort
Follow-up
median 3.7 years (interquartile range 3.4 to 4.3 years)

Supports TAVI durability to ~4 years in high-risk patients; extends observational data but leaves open need for longer randomized confirmation.

Does transcatheter aortic valve implantation provide durable valve function and survival in high-risk patients declined for surgery?
Transcatheter aortic valve implantation demonstrates good medium- to long-term durability and preserved hemodynamic function with no structural failure up to 3-4 years in high-risk surgical candidates.
Gurvitch et al. (2010) conducted a cohort in Aortic stenosis (n=89). Transcatheter aortic valve implantation was evaluated on Overall survival. Transcatheter aortic valve implantation in high-risk patients showed 51% overall survival at median 3.7 years, with preserved hemodynamic function and no structural valvular deterioration.
