dior j adior patent calfskin slingback|J'Adior Slingback Pump Black Patent Calfskin 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] 3 - LVEDD 3)]} + 0.6; where. LVEDD = LV end-diastolic dimension (mm) Subscribe
