LV Mass Index

Echocardiographic LV Mass Estimator • Devereux et al.

IVS (mm)
LV Int. Dia. (mm)
Post. Wall (mm)
BSA (m²)

Ready for Dimensions

Input echocardiographic measurements to determine LV hypertrophy severity.

Guidelines & Evidence

Last Review: 2026-07-17

When to Use

When to Use

Assessment of Left Ventricular Hypertrophy (LVH) in newly diagnosed or refractory hypertensive patients.
Monitoring the reversal of LVH in response to intensive antihypertensive or structural (valvular) therapy.
Risk stratification in patients with subclinical target organ damage.
Differentiation between physiologic hypertrophy (athlete's heart) and pathologic remodeling.

How it Works

Devereux Formula

LVM = 0.8 × (1.04 × ((IVST + LVID + PWT)³ - LVID³)) + 0.6 LVMI = LVM / Body Surface Area (BSA)

ASE Guideline Thresholds (g/m²)

Severely Abnormal≥ 122≥ 149

Clinical Pearls

Indexing Limitations

In obese patients, standard indexing by BSA may underestimate the severity of LVH because excess adipose tissue bloats the denominator. Consider indexing to height (m^2.7) or utilizing Body Fat Percentage distributions instead.
M-mode heavily relies on geometric assumptions (that the ventricle is a prolate ellipse). If shape is significantly distorted (e.g. basal septal bulge or asymmetric remodeling), 3D echocardiography or Cardiac Magnetic Resonance (CMR) offers significantly improved accuracy.
Age and gender independently impact normal ranges. While Japanese and American cohorts show no racial variations in 3DE studies, significant divergence still occurs strictly by biological sex.

The Evidence

Primary References

Normal Values of Left Ventricular Mass Index Assessed by Transthoracic Three-Dimensional Echocardiography.

Mizukoshi K et al. • J Am Soc Echocardiogr.. 2016;Demonstrated superior accuracy of 3DE vs CMR for LV mass quantification, confirmed age/gender dependence, and ruled out ethnic variability between Japanese and American patient populations. https://doi.org/10.1016/j.echo.2015.09.009

The relationship between left ventricular mass index and body composition in new-diagnosed hypertensive patients.

Karakan S et al. • Clin Hypertens.. 2015;Proved independent association of Body Fat Percentage (BFP) and higher LVMI in normotensive to newly hypertensive patients. Strongly advocates correcting for adipose influence. https://doi.org/10.1186/s40885-015-0033-6
