cardiology

Background: Left ventricular ejection fraction (LVEF) is the most commonly used clinical measure of systolic function and is a powerful predictor of outcomes. Current guidelines recommend using the biplane method of discs (MOD) (modified Simpson’s rule) to measure LVEF however the accuracy of this measurement is dependent on endocardial border detection and orthogonal, on-axis biplane imaging, and studies report both inter and intraobserver variability.
