Implication
Ejection time assessment requires caution in low-output AS; leaves open its utility for severity grading by ventricular function.

Outcome
Relations among rate-corrected left ventricular ejection time, aortic valve area, and determinants of ventricular performancesurrogate
Left ventricular ejection time in severe aortic stenosis has a multifactorial basis and is less prolonged and unrelated to valve area in patients with failing ventricles compared to those with normal cardiac index.
