Assessment of the Left Ventricle

Linear Measurements

Parasternal long-axis or short-axis views

2D or M-Mode (preferably 2-D guided)

Measure at level of mitral leaflet tips

Care must be taken not to foreshorten

IVS, LVID, PW: use blood tissue interface as a boundary

End-diastole

-largest dimension, or frame after mitral closure

End-systole

-smallest dimension, or frame preceding mitral valve opening

Linear Measurements

Linear Measurements

Ideal to average over several cardiac cycles

Beware of the RV portion of septum, moderator band, and chordae in LV: may cause overestimation of wall thickness

M-Mode measurements larger than 2D (ULN LVIDd 5.5 cm vs. 5.2 cm)
