WebMar 26, 2015 · Objective: Assessment of ejection fraction (EF) results from Simpson’ method from 2D and 3D transthoracic echocardiography (TTE). In addition, it was also assessed stroke volume (SV) from 2D TTE and 3D TTE. Background: The reference method to calculate LV volumes, SV and EF is cardiac magnetic resonance imaging (MRI). … WebAn ejection fraction (EF) is the volumetric fraction (or portion of the total) of fluid (usually blood) ejected from a chamber (usually the heart) with each contraction (or heartbeat).It can refer to the cardiac atrium, ventricle, gall bladder, or leg veins, although if unspecified it usually refers to the left ventricle of the heart.
