Site-dependency of the E/e' ratio in predicting invasive left ventricular filling pressure in patients with suspected or ascertained coronary artery disease

Abstract

In patients with CAD, E/e'L is the most accurate parameter in predicting abnormally increased LVFP.

Effect of Echocardiographic Grading of Left Ventricular Diastolic Dysfunction by Different Classifications in Primary Care

“…Beyond site-related discrepancies for the measurement of E/e', 27 such lack of concordance could be explained by the presence of only 1 of the 2 required measures for moderate or severe DD by Olmstead County method or by the lack of load challenging by Valsalva maneuver and longer DT cutoff by Canberra Study method and, finally, by the presence of inconsistent criteria for the ASE/EAE convention, providing a large number of parameters, without neither suggesting a hierarchical approach for their use nor a minimal number of criteria for assignment of a specific pattern. Overall, patients with undetermined DD were characterized by increased E/e', worse LV systolic longitudinal function and reduced relaxation, and lower AR Dur À A Dur according to Olmstead County and ASE/EAE methods.…”

Additional value of lateral tissue Doppler imaging in the assessment of diastolic dysfunction among subjects with pseudonormal pattern of mitral inflow

“…Park and colleagues showed that septal TDI tends to overestimate the severity of LV diastolic dysfunction when compared with lateral TDI, and suggested that lateral TDI measurements more accurately reflects LV diastolic dysfunction than septal TDI measurement do [14]. Other studies have also reported that lateral TDI correlates best with LV filling pressure and with indices of LV stiffness in subjects with normal ejection fraction or coronary artery disease [19-21]. Current guidelines recommend the use of average e’ obtained from septal and lateral sides of the mitral annulus for prediction of LV filling pressure [10].…”

Exercise stress echocardiography with tissue Doppler imaging in risk stratification of mild to moderate aortic stenosis

“…the early diastolic mitral annular velocity, the E/e 0 ratio, represents a more accurate parameter in predicting different levels of LVFP. Various authors have suggested the prognostic role of E/e 0 ratio in different cardiac disorders [30][31][32][33][34][35].…”
