LOINC long common name : Left ventricular Myocardial mass/Height exp 2.7 [Mass/Area] by US.2D Calculated by
truncated ellipsoid method;
LOINC short name : LV Myo/Ht exp 2.7 US.2D trunc ellips;
LOINC description : The myocardial index is the left ventricular (LV) mass normalized for body size, which
can be approximated by different measures including body surface area (BSA) and height.
This term represents an index based on height 2.7. Left ventricular mass calculated
by the truncated ellipsoid formula on 2D ultrasound is as follows: 1.05 * Pi * {(b
t) 2 * [2/3 * (a t) d-d 3/(3 * (a t)) 2] - b 2 * [2/3 * a d - d 3/(3 * a 2)]}, where
a distance from the minor axis to the endocardium at the LV apex, b LV minor radius,
t mean wall thickness, and d distance from the minor axis to the mitral valve
plane. [PMID: 25559473];
