Ejection Fraction

Esther Donohue B.S., RDMS, RDCS, RVT

Visual estimation can be used to gauge left ventricular ejection fraction (LVEF), a method subject to inter-observer variability and inaccuracy. M-mode E-point septal separation (EPSS), the minimum separation between the anterior mitral valve leaflet and the interventricular septum, offers a more objective measure of LVEF. The EPSS is easily obtained and is a quantitative predictor of systolic dysfunction.
