Discordant Aortic Stenosis: Low-Gradient and Low-Flow Patterns in the Echo Lab

When AVA, velocity, and gradient don’t agree, know what to check next.

1.0 AMA PRA Category 1 Credit™

Aortic stenosis grading is usually straightforward when AVA, peak velocity, and mean gradient agree. The challenge begins when they do not.

This course provides a practical, step-by-step approach to discordant and low-gradient AS. You’ll learn how to verify the measurements, classify the flow-gradient-LVEF pattern, select the appropriate next step, and report the findings clearly.

Clinical examples walk through reduced-EF low-flow, preserved-EF low-flow, and normal-flow low-gradient AS, including the appropriate roles of low-dose DSE and CT aortic valve calcium scoring.
