Observed Survival in the TAVI Cohort versus the General Population Across Age Subgroups. These survival curves are subdivided into different age groups as visible in the top. In the bottom the postprocedural period is excluded to demonstrate the effect of improvements in pre-, peri- and postprocedural care. There is no difference in survival between the transcatheter aortic valve implantation (TAVI) group aged 80 years and older and the general population. Excluding the first 30 days reveal that the TAVI group aged 80 years and older does better. In all other cases the general population fairs better. Differences shown as p values are calculated with the log-rank test.
