From: Longitudinal wall fractional shortening: an M-mode index based on mitral annular plane systolic excursion (MAPSE) that correlates and predicts left ventricular longitudinal strain (LVLS) in intensive care patients

Fig. 3

MAPSE and ventricular length obtained by conventional M-mode. a Schematic diagram of M-mode through the mitral annuli at end-diastole in the A4C view (white dashed line). M-mode ventricular length (MMVL) is the distance between the apex of the LV, where the cursor intersects the pericardium, to the mitral annulus at end-diastole. b An example of M-mode of the lateral wall in A4C view. Note the “static” horizontal lines at the top (superficial) layer are the body wall and muscle layer. LV left ventricle, MAPSE mitral annular plane systolic excursion, MMVL M-mode ventricular length
