Figure 2. Kaplan-Meier Estimates for Events in Patients With Severe Aortic Stenosis According to Left Ventricular Ejection Fraction (LVEF) and Peak Aortic Jet Velocity.
Kaplan-Meier analyses of overall survival in patients with severe aortic stenosis at baseline as a function of peak aortic jet velocity (A) and LVEF (B).
aSignificant difference with peak aortic jet velocity of 5 m/s or greater.
bSignificant difference with LVEF less than 60%.
cSignificant difference with LVEF of 60% to 65%.
