May 26, 2021 · The E-Point Septal Separation (EPSS) is an easy measurement to obtain that is accurate in estimating the LVEF. EPSS is measured in the parasternal long axis view (PLAX) of the heart, which gives a view of the left ventricle and is often used to assess its function.

According to cardiac MRI data, EPSS measurements <8mm are considered to have a normal LVEF while distances, 8-18mm are mild/moderately reduced EF, and >18mm are suggestive of severely reduced LVEF (Elagha 2012).

Oct 14, 2020 · ED physicians can assess left ventricular systolic function using the EPSS, and EPSS is strongly correlated with calculated LVEF. An EPSS greater than 7 mm may be used to predict patients with severely reduced LVEF.

The EPSS measurement by cardiac MRI is an easy and reliable method, which allows parallel assessment of LV function, in patient with and without myocardial fibrosis. The EPSS can generate a rapid quantitative idea on LV function, especially when acquisition of multiple breath-hold short-axis images is difficult.

A normal EPSS is < 1cm (measured on M-mode), which has a high sensitivity for abnormal LV ejection fraction. An EPSS <1 cm is very unlikely to be accompanied by abnormally functioning LV. There are a number of caveats to EPSS (e.g. mitral stenosis, regional wall motion abnormalities), so EPSS should not be relied upon in isolation.

Jul 22, 2022 · EPSS is the measured distance between the “e-point” and the interventricular (IV) septum. The e-point corresponds with the point in time when the mitral valve is opened maximally. In a normal functioning heart, the mitral valve should nearly strike the …

An EPSS distance of <7mm is considered normal. EPSS <7mm suggests normal systolic function, with increasing distances correlating with more severe systolic dysfunction (lower EF). A EPSS > 13mm suggests mod-severely reduced EF <35%.

An EPSS <5 mm is highly predictive of a normal ejection fraction, and an EPSS >10 mm is even more predictive of a reduced ejection fraction. The EPSS is a valuable clinical predictor of a normal or depressed ejection fraction regardless of abnormalities of septal motion.

The normal range for LVEDV is wide (106-214 mL in men and 86-178 in women) because it is body size dependent. Formal labs divide the raw value by body surface area to create an index, but we rarely have an accurate BSA.

Jul 1, 2017 · End point septal separation (EPSS) is the use of M-mode in the parasternal long cardiac window to evaluate the distance between the anterior leaflet of the mitral valve and the interventricular septum in end diastole. EPSS >1.2 cm is considered abnormal and is associated with poor ejection fraction.
