Mitral valve E point-septal separation as an index of left ventricular function with valvular heart disease.
Echocardiographic mitral valve E point-septal separation (EPSS) has been found to be a useful hemodynamic index. Prior studies have shown a high negative correlation between EPSS and left ventricular ejection fraction (EF) in selected patients, but the utility of this index with valvular heart disease has not been examined in detail. Cardiac catheterization and M-mode echocardiographic data wer...
متن کاملMitral-septal separation: new echocardiographic index of left ventricular function.
San Francisco, California An echocardiographlc measurement of the minimal separat ion between the anterior mitral valve leaflet at its E point and the interventr icular septum was evaluated as an index of left ventricular function. Mitral-septal separation was found to be easily measured, reproducible and Independent of patient position or heart rate changes of up to 32 beats/rain. In a group o...
متن کاملMitral valve E-Point to Septal Separation (EPSS) measurement by cardiac magnetic resonance Imaging as a quantitative surrogate of Left Ventricular Ejection Fraction (LVEF)
Background Using Echocardiography, the mitral Valve E-Point to Septal Separation (EPSS) is a straightforward approach that roughly corresponds to the status of left ventricular (LV) function, but its use has been limited to echocardiography and without solid quantitative correlation to left ventricular ejection fraction (LVEF). It may also cause underestimation of EF due to endocardial echo dro...
متن کاملQuantitative estimation of left ventricular ejection fraction from mitral valve E-point to septal separation and comparison to magnetic resonance imaging.
This study tested the hypothesis that the mitral valve E point-to-septal separation (EPSS) can be used to quantify the left ventricular (LV) ejection fraction (EF) on a continuous scale rather than simply as "normal" or "reduced." After excluding 5 patients with mitral valve prostheses, asymmetric septal hypertrophy, or significant aortic insufficiency, EPSS was measured in 42 patients by 3 ind...
متن کاملEchocardiographic assessment of left ventricular function in mitral valve disease.
Echocardiography was used to study left ventricular size and contraction in 90 patients with isolated mitral valve disease--47 patients with mitral stenosis, 26 with mixed mitral valve disease and 89 with mitral regurgitation. Left ventricular measurements included the end-diastolic internal dimension (LVIDd), mural thickness (PWTd), an index of circumferential myocardial contraction--fractiona...
