In the neonatal and pediatric intensive care setting, bedside cardiac ultrasound
is often used to assess ventricular dimensions and function. Depending upon the
underlying disease process, it is necessary to be able to evaluate the systolic
and diastolic function of left and or right ventricles. The systolic function of
left ventricle is mostly assessed qualitatively on visual inspection
"eye-balling" and quantitatively by measuring circumferential fraction shortening
or calculating the ejection fraction by Simpson's planimetry. The assessment of
left ventricular diastolic function relies essentially on the mitral valve and
pulmonary venous Doppler tracings or tissue Doppler evaluation. The right
ventricular particular shape and anatomical position does not permit to use the
same parameters for measuring systolic function as is used for the LV. Tricuspid
annular plane systolic excursion (TAPSE) and S' velocity on tissue Doppler
imaging are more often used for quantitative assessment of right ventricle
systolic function. Several parameters proposed to assess right ventricle systolic
function such as fractional area change, 3D echocardiography, speckle tracking,
and strain rate are being researched and normal values for children are being
established. Diastolic function of right ventricle is evaluated by tricuspid
valve and hepatic venous Doppler tracings or on tissue Doppler evaluation. The
normal values for children are pretty similar to adults while normal values for
the neonates, especially preterm infants, may differ significantly from adult
population. The normal values for most of the parameters used to assess cardiac
function in term neonates and children have now been established.
