Diastolic function can be estimated from E/A ratio, e’ and deceleration time (DT). These three methods, as well as several supplementary methods, will now be discussed in detail. Flow velocity across the mitral valve is examined in the apical four-chamber view (A4C) using pulsed Doppler.

In the majority of clinical studies, LV filling pressures and diastolic function grade can be determined reliably by a few simple echocardiographic parameters with a high feasibility. In addi-tion, technical developments have emerged that provide new indices that appear promising for studying LV diastolic function.
Diastolic Function Assessment in the Presence of a Normal LVEF (Figure 8A) The presence or absence of diastolic dysfunction in patients with a normal LVEF is based on the assessment of four variables.
•Know correlation between Echo diastolic parameters and underlying hemodynamics •Appreciate how 2016 Guideline was created •Understand pitfalls of Echo diastolic function assessment •Classify and grade diastolic function •Estimate filling pressure reliably in most patients at rest and with exercise
LV diastolic function determines symptoms and predicts outcome in patients with cardiovascular disease. Echocardiography is used to assess LV diastolic function, and estimate LV filling pressures.
that govern the timings and pressure dierentials that enable ventricular lling, and to appreciate the impor-tance of systolic/diastolic interdependence, it is essential to understand ventricular function throughout the car-diac cycle and how this determines lling, lling pressure (LVFP) and ejection. Left ventricular systole
The assessment of left ventricular (LV) diastolic function should be an integral part of a routine examination, particu-larly in patients presenting with dyspnea or heart failure. About half of patients with new diagnoses of heart failure have normal or near normal global ejection fractions (EFs).
