Left ventricular mass index

Radiopaedia • CC-by-nc-sa 3.0 • de

Left ventricular mass index (LVMI) is a parameter used in echocardiography and cardiac MRI.

LVMI is calculated using the following equations:

  • LVMI = LVM (left ventricular mass)/body surface area
  • left ventricular mass =  0.8{1.04[([LVEDD + IVSd +PWd] - LVEDD)]} + 0.6

where

  • LVEDD = LV end-diastolic dimension (mm)
  • IVSd = interventricular septal thickness at end-diastole (mm)
  • PWd = posterior wall thickness at end-diastole (mm)
