There are elevated filling pressures if any of the following are true:
If average E/e’ is unobtainable or not used routinely in your lab, use “septal E/e’ >15” or “lateral E/e’ >13” to determine elevated filling pressures.
IVRT/T E-e’ refers to the isovolumic relaxation time divided by the time interval between the onset of mitral inflow and onset of mitral annular velocities. (Match R-R intervals)

There is limited data regarding diastolic function and severe AI, however the presence of the following suggests increased filling pressures:
If average E/e’ is unobtainable or not used routinely in your lab, use “septal E/e’ >15” or “lateral E/e’ >13” to determine elevated filling pressures.
ASE mentions that pulmonary hypertension is caused by non-cardiac etiology if lateral E/e’ <8. However, it is caused by a cardiac etiology if lateral E/e’ > 13. Notice that there is no mention of septal e’ nor the average of both.
No single parameter is useful for determining diastolic dysfunction in this case. Some indicators, especially when combined, which may suggest elevated filling pressures in a transplant include:
Lastly, some notable information mentioned by ASE pertains to:
