Left ventricular Myocardial mass/Body surface area [Mass/Area] by US.M-mode+Calculated by cube method

LV Myo mass/BSA US.M-mode+cube

Definition

The myocardial index is the left ventricular (LV) mass normalized for body size, which can be approximated by different measures including body surface area (BSA) and height. This term represents a BSA-based index. BSA can be calculated by a number of methods including the Mostellar and Du Bois formulas, or in some cases the average adult BSA, 1.73 m2, is used by default. The cube function is a method for calculating left ventricular mass from M-mode echocardiography measurements and assumes a long- to short-axis length ratio of 2:1. The formula is as follows: LV mass = 1.04(IVSd + LVIDd + PWTd)^3 - LVID^3), where IVSd = interventricular septal thickness, LVIDd = left ventricular internal diameter (short axis), and PWTd = posterior wall thickness, all measured during end-diastole.
