Scatterplot illustrating the association between age and TVG. The regression equation demonstrated, TVG = × Age (in years). (TVG = transvalvular gradient.)

3. Fig 2
Kaplan-Meier curves comparing medium-term outcome in patients with TVG more than 100 mm Hg and those with TVG less than or equal to 100 mm Hg. Survival time was ± 1.5 months and ± 1.23 months, respectively (log rank value of 0.01 and p = 0.92). (TVG = transvalvular gradient.)

4. Fig 3
Kaplan-Meier curves comparing medium-term outcome in patients receiving a valve size > 19 with those receiving a valve size = 19. Survival time was 42.6 ± 0.89 months and 36 ± 3.6 months, respectively (log rank value of 5.61 and p = 0.017).
