LV Analysis, Morphology
Mass index, 2d
Fig. 1 Transthoracic parasternal short axis view. Red: tracing of pericardial border to obtain A1. Green: tracing of endocardial border (papillary muscles are excluded) to obtain A2. Am = A1 – A2 = area of myocardium
t: myocardial thickness (automatically calculated by the software).
LV mass index (truncated ellipsoid) normal values:
Males: 76±13 gm/m2
Females: 66±11 gm/m2
Fig. 2. Transthoracic subcostal 4-chamber view .a: semi-major axis from widest minor axis radius (b) to apex; b: short axis radius; d:truncated semi-major axis from widest minor axis radius (b) to mitral anulus plane.
LA: left atrium; RA: right atrium; RV: right ventricle
