Early diastolic mitral annular velocity at the interventricular septal annulus correctly reflects left ventricular longitudinal myocardial relaxation

Abstract

IS-e' well reflected LV longitudinal myocardial relaxation and LV diastolic function, and was found to be more useful in evaluating LV diastolic function than LW-e'.

Galectin-3 als neuer Biomarker diastolischer Funktionsstörung bei Hämodialysepatienten

“…Early mitral annular velocity (E') obtained by tissue Doppler imaging is used to determine LV diastolic function because it is accepted to reflect well LV longitudinal myocardial relaxation, despite some controversy [25,34]. Because of their inverse correlation, we suggest that increased levels of gal-3 can be useful as an indicator of deterioration in myocardial relaxation.…”

In juvenile dermatomyositis, cardiac systolic dysfunction is present after long-term follow-up and is predicted by sustained early skin activity

“…Both E/e′25 and e′ are commonly used parameters reflecting LV diastolic function. However, recent publications and clinical experience suggest that e′ alone is simpler and equally reliable to E/e′ 26. Therefore, in the present paper we have used e′ alone as parameter of diastolic function.…”

Electromechanical Relationship in Hypertrophic Cardiomyopathy

“…3): Systolic velocity (Sm), systolic strain rate (sSR), and systolic strain (S) which reflect global and regional contractile function [19–23]; early diastolic velocity (Em) and strain rates (eSR) which provide information about global and regional relaxation properties [24–28]; late diastolic velocity (Am) and strain rate (aSR) which are determined by left atrial d P /d t , left atrial relaxation, LV end-diastolic pressure, and LV stiffness [26, 29]; and ratio of Mitral E velocity to Em (E/Em) which correlates well with mean pulmonary capillary wedge pressure and hence is an estimate of LV filling pressure [24]. …”
