S′ Wave in 2025: New Grading, Measurement Tips, and Pitfalls
October 27, 2025

Few measurements in echo are as quick and powerful as the S′ velocity. With a single tissue Doppler tracing of the tricuspid annulus, we can quickly gauge whether the right ventricle is pulling its weight.
In echocardiography, Fractional Area Change (FAC) is one of the most reliable 2D measures of right ventricular (RV) systolic function, offering a comprehensive view of right ventricular performance.
Learn how to measure TAPSE correctly, apply the new grading, recognize common pitfalls, and interpret results within the broader right-heart framework.
Before we dive further into the 2025 ASE Right Heart Guidelines, let’s zoom out for the big picture understanding of pulmonary hypertension in echo.
This week, we’re focusing on the most significant updates to the 2025 ASE Right Heart new severity grading, and what they mean for your echo lab.
