LV Mass and LV Mass Index

Left ventricular mass and left ventricular mass indexed to body surface area estimated by LV cavity dimension and wall thickness at end-diastole.

Relative wall thickness (RWT) allows further classification of LV mass increase as either concentric hypertrophy (RWT >0.42) or eccentric hypertrophy (RWT ≤0.42).

LV Mass (g) = 0.8{1.04[([LVEDD + IVSd +PWd]3 - LVEDD3)]} + 0.6
