LOINC long common name : Left ventricular Myocardial mass/Body surface area [Mass/Area] by US.2D Calculated
by truncated ellipsoid method;
LOINC short name : LV Myo mass/BSA 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 a BSA-based index. BSA can be calculated by a number of methods
including the Mostellar and Du Bois formulas, or in some cases the average adult BSA,
1.73 m2, is used by default. 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];
