Observed Survival in the TAVI Cohort versus the General Population. These survival curves reveal the difference in survival of the total transcatheter aortic valve implantation (TAVI) population versus the general Dutch population. In panel B the first 30 days of the postprocedural period are excluded to demonstrate the effect of improvements in pre-, peri- and postprocedural care. Differences shown as p values are calculated with the log-rank test.
