The following commonly used echocardiographic indexes should also be expanded at first mention but are included here for reference:

Term

Expansion

AVA

aortic valve area

EF

ejection fraction

EPSS

E point septal separation

FAC

fractional area change

FS

fractional shortening

IVS, IVST

interventricular septal thickness

LVID

left ventricular internal dimension

MVA

mitral valve area

PHT

pressure half-time

PW, PWT

posterior wall thickness

RVID

right ventricular internal dimension

SAM

systolic anterior motion of the mitral valve

d or ed

end diastole

s or es

end systole

Terms are combined as in the following examples:

IVSd

IVSs

LVIDd

LVIDed

LVIDes

LVIDs

LVPWd

LVPWs

RVIDd

Ejection fraction is expressed as a percentage, eg, 60% (see also 19.0, Numbers and Percentages).
