Figure 6. Hazard ratio (HR) and 95% CI for risk of overall mortality associated with ratio of acceleration time/ejection time ≤0.35 or >0.35 in subgroups of patients with high‐gradient severe aortic stenosis and no or mild symptoms.

AF indicates atrial fibrillation; AVA, aortic valve area; BSA, body surface area; CAD, coronary artery disease; LV, left ventricular; LVEF, LV ejection fraction; LVH, LV hypertrophy; MPG, mean aortic pressure gradient; NYHA, New York Heart Association; SVi, stroke volume index; and Vmax, aortic peak jet velocity.
