Which two-dimensional method is recommended for assessing left ventricular ejection fraction when regional wall motion...

The Simpson biplane method (method of disks) is the recommended two-dimensional echocardiographic technique to quantify left ventricular ejection fraction (LVEF), especially when regional wall motion abnormalities are present. It involves tracing endocardial borders in apical two- and four-chamber views to calculate LV volumes and EF, accounting for segmental dysfunction.

Visual estimation is subjective and less accurate. The Quinones method (single plane area-length) and Teichholz method rely on geometric assumptions and are less accurate in abnormal ventricles.

ASE chamber quantification guidelines strongly endorse Simpson biplane for LVEF assessment in regional wall motion abnormalities【12:ASE Chamber Quantification Guidelines†p.70-75】【16:Textbook of Clinical Echocardiography, 6e†p.60-65】.
