Tissue Doppler velocity a' of LV free wall

peak E-Wave velocity, peak A-Wave velocity, MV DT, E/A, Tissue doppler - E' and A', E/E', E/DT,...

Trans mitral early and late diastolic velocity ratios have been most extensively studied and used for assessing LV diastolic function. However, it has its limitations. Therefore other adjuncts have been used- E- deceleration time, isovolumic relaxation time, E/E', pulmonary vein S and D. The dimension-volume of the left atrium has been proposed as an index of diastolic function but also has its caveats.

I think that this algorythm will be useful to evaluate LV diastolic function.

All parameter can be used. Each parameter has got it's own merits and demerits. Which parameter should be used that also depends upon the underlying condition of heart. Mitral annular relaxation velocity or Ę' has got prognostic significance. E/E'en has shown to correlate with left ventricular filling pressure. The utility of standard Ę and A wave ratio have been questioned.Very short mitral DT suggest restrictive physiology and severe diastolic dysfunction. Grading of diastolic dysfunction can be done using tissue Doppler based velocities, pulmonary venous Doppler and left atrial size. Diastolic parameter should be adjusted with aging..

E/A ratio

Usually E/A, E wave deceleration time, E/e' septal and lateral, Left Atrial indexed volumme and Left Atrial diammeter

 Left atrium  inexed volume

Left ventricular mass index

E/A and E wave deceleration time,

ratio  E/e septal

All the answers above are correct, i only want to add that you have also to measure inferior vena cava because the endovascular volume affects the result of transmitral flow.

I confirm all of above. Some time it is depend on clinical case.

We guided by local protocol.

E/A ratio works as a good triage marker but you should use all those. Sometimes they are not available so at least 2 in 3 or 3 in 4 have to be positive do diagnose diastolic disfuction.

Good update: Recommendations for the Evaluation of Left Ventricular Diastolic Function by Echocardiography: An Update from the American Society of Echocardiography and the European Association of Cardiovascular Imaging. Especially examples in pictures.

If you vote: number 1 - E/A ratio...

Transmitral flow velocity profile (E/A, IVRT, DT), tissue Doppler for e' or E/e', LA volume or diameter or pulmonary vein flow velocity profile (s, d, s/d and Ar duration).  Though a bit old, I found this article useful as well.

Conventional E/A ratio is the widely used parameter to determine diastolic function but it is a liite bit late predictor. Tissue doppler are as rapid and easy but can detect earlier diastolic dysfunction

Е/A, E/e', and left atrial volume are routinely assessed.

You should also remember that, as RA Nishimura noted, the diastolic function is clinician’s Rosetta Stone.

depending on the echocardiography machine being used. The latest technology is actually emphasizing on the use of tissue Doppler which older machines may not have. The other conventional markers such as E/A ratio, deceleration time, isovolumic relaxation time combined with pulmonary venous and hepatic systolic : diastolic flow must be combined to determine the diastolic parameters using echocardiography.

Most commonly used is E/e. It is the easiest to perform. Though more time consuming LAVI is very useful and prognostically very valuable. Simple mitral inflow spectral display of a restrictive filling immediately suggests that L.A. pressures are high. Whenever possible several parameters should be combined.

The assessment of LV diastolic function by echocardiography should be performed by calculating peak E-wave velocity, peak A-wave velocity, MV E/A ratio, mitral E/e, LA maximum volume index (mL/BSA),and TR systolic jet velocity (m/sec) by 2D and Doppler methods. The advantages and limitations of these variables used to assess LV diastolic function should also be considered (please see Nagueh SF, Smiseth OA, Appleton CP, et al. Recommendations for the Evaluation of Left Ventricular Diastolic Function by Echocardiography: An Update from the American Society of Echocardiography and the European Association of Cardiovascular Imaging. J Am Soc Echocardiogr. 2016: 29(4):277-314).

Does strain have any value in the study of left ventricular diastolic function?

 Dear Isaac, yes strain rate echo can be used to access diastolic function of LV. E/SRE ratio can be used to access diastolic function of LV... Thanks

The combination of isovolumic relaxation time, deceleration time and E/A ratio remains a veritable option to characterize diastolic dysfunction. Next in line is the tissue Doppler ratio  of E/E'.
