Kaplan-Meier estimates are provided at 2 years (day 730) and use the first event per patient. Events occurring after
730 days are not included in the analysis.
b. Key Secondary Endpoints for Labeling
The results for the six key secondary endpoints for labeling using the Hochberg’s step-up
method for multiple tests are presented for the ITT population in Table 25 and for the as-
treated (AT) population in Table 26. SAPIEN XT was found to be non-inferior to SAVR in
NYHA class at 2 years, DAOH to 2 years, 6MWT distance at 2 years, and EOA at 2 years.
The 6MWT distance at 2 years was superior to that at baseline in the SAPIEN XT patients.
