How To: Measure Simpson's Biplane Accurately

Aram K.’s latest post walks clinicians through the step‑by‑step process for measuring left‑ventricular ejection fraction using the Simpson’s biplane method on 2D echocardiography. It stresses acquiring both apical four‑chamber and two‑chamber views, precise endocardial tracing at end‑systole and end‑diastole, and optimal machine settings to avoid foreshortening. The guide also highlights common pitfalls, reproducibility tips, and when to cross‑check results with three‑dimensional echo. By standardizing these techniques, the article aims to improve EF accuracy across cardiac labs.
