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 |

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 |

Terms are combined as in the following examples:
IVSd
IVSs
LVIDd
