In patients with normal ER does septal or LV filling pressures.
Lateral tiisue E/e' or e'/a' best corellation with normal EF. E/e' ratio is not accurate as an index of filling pressures in normal subjects or in patients with heavy MAC, MV disease and constrictive pericarditis.
septal e' < 8mm or lateral e' indicates
LV diastolic dysfunction
RV EDd normal
RV EDd mild abn
RV EDd mod abn
RV EDd sev abn
RV free wall thickness normal
PA diameter normal
Normal 1.5-2.1 cm
PA diameter mild abn
PA diameter mod abn
PA diameter sev abn
Pulm vein indicators for increased LVEDP
PV a vel > 0.35
PV a dur - MV A dur >20ms
What is normal LVEDP
Holodiastolic reversal flow in descending aorta but not abd aorta indicates.
Mod to severe AR.
Reversal in both c/w severe AR
Increased LV relative wall thickness with normal LV mass index.
Elevated LV mass index with high relative wall thickness.
Elevated LV mass index
Men >115 g/m2
Women >95 g/m3
Mitral E wave velocity is expected to be low in MS. (T or F)
False. In mitral stenosis, the peak velocity of the mitral E wave is expected to be high
SR = (V1 − V2)/L
strain rate (SR) is defined as the change in velocity between two points divided by the distance between the two points at the end of systole (L).
