Why Ejection Time Matters in Aortic Stenosis

Shifting the focus to ejection dynamics to improve AS report accuracy

When evaluating aortic stenosis, we rely heavily on velocity, gradients, and valve area. But in asymptomatic patients and those with low-gradient severe AS, these metrics often fail to tell the whole story.

This lesson shifts the focus to ejection dynamics—specifically how long the ventricle can sustain systolic ejection—and why this physiologic insight …
