LV Mass Index & Geometry (Devereux)
LV mass (Devereux 1986) indexed to BSA, with relative wall thickness and the four-pattern ASE/EACVI geometry classification (Lang 2015).

Example
- LV internal diameter, end-diastole
- 5.2 cm
- Posterior-wall thickness, diastole
- 1.2 cm
- Septal-wall thickness, diastole
- 1.2 cm
- Body surface area
- 2.0 m^2
- Sex
- Male
Result: LV mass 248.8 g; LVMI 124.4 g/m²; RWT 0.46 — concentric hypertrophy.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Geometry
- RWT 0.42 cutoff × sex-specific LVMI limit (men > 115, women > 95 g/m²): normal, concentric remodeling, eccentric hypertrophy, concentric hypertrophy.
What you enter
- LV internal diameter, end-diastole (LVIDd)
- Posterior-wall thickness, diastole (PWTd)
- Septal-wall thickness, diastole (IVSd)
- Body surface area
- Sex
How this is calculated
- Formula
- LV mass = 0.8·{1.04·[(LVIDd + PWTd + IVSd)³ − LVIDd³]} + 0.6 (cm); LVMI = mass/BSA; RWT = 2·PWTd/LVIDd.
