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.
There are elevated filling pressures if any of the following are true:
If mitral e’ > 8 cm/s then consider constrictive pericarditis. Also consider constrictive pericarditis if lateral e’ is less than septal e’.
Hepatic vein end-diastolic reversal velocity (measured on expiration) divided by forward flow velocity is definite constrictive pericarditis if > 0.8. Restrictive cardiomyopathy will have septal e’ < 6 cm/s.
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.
