Mitral Valve E-Point Septal Separation as an Indicator of Ejection Fraction

The mitral valve E-point septal separationThe mitral valve E-point septal separation (EPSS) is widely used clinically as an M-mode echocardiographic indicator of a normal or abnormal left ventricular ejection fraction. However, no study has examined systematically the utility of the EPSS in predicting normality of ejection fraction in patients with a reversed septal motion which is often observed in patients with right ventricular volume overload states or right ventricular disease (either primary or due to pulmonary disease). If valid, this measurement would have significant clinical importance because other conventional M-mode echocardiographic correlates of ejection fraction, such as fractional shortening, are not useful in patients with reversed septal motion. Therefore, the purpose of this study was to compare the utility of the EPSS as an indicator of a normal or abnormal ejection fraction in patients with normal and reversed septal motion.
