Fig 4 Effect of aortic valve replacement (AVR) on survival as a function of mean transaortic gradient in low EF patients. (A) EF ≤ 0.35, MG ≤ 30 mm Hg; (B) EF ≤ 0.35, MG > 30 mm Hg.

Fig 6 Sensitivity analysis with persistent aortic valve replacement (AVR) benefit with patients with events until 2 years eliminated in the low gradient group. (A) Patients events in ≤ 30 days eliminated; (B) Patients events in ≤ 90 days eliminated; (C) Patients events in ≤ 1 year eliminated; (D) Patients events in ≤ 2 years eliminated.

Fig 7 Effect of aortic valve replacement (AVR) on survival as a function of left ventricular ejection fraction (EF) in the low gradient group. (A) Severe aortic stenosis (AS), low gradient, EF < 0.35; (B) severe AS, low gradient, EF 0.35 to 0.54; (C) Severe AS, low gradient, EF ≥ (AS = aortic stenosis.)
