Abstract
In the neonatal and pediatric intensive care setting, cardiac point of care ultrasound (POCUS) is very useful to assess left ventricular dimensions and function. Systolic function can be easily assessed qualitatively by visual assessment (often referred as “eyeballing”). Left ventricle quantitative assessment on echocardiography can be done by measuring fractional shortening (FS) on M-mode or measuring ejection fraction (EF) by 2D imaging planimetry. Other semi-quantitative tools may be useful to bedside providers, but are considered advanced applications including tissue Doppler systolic wave assessment, myocardial performance index (Tei index), and dP/dt of mitral regurgitation. Ventricular diastolic function, evaluated using Doppler and Tissue Doppler, is also an advanced application and beyond the scope of basic point of care ultrasound but an important component of comprehensive echocardiography. This chapter identifies methods of left ventricular contractility assessment that may be beyond the scope of the basic cardiac POCUS applications, though relevant within the scope of communicating with experts and in understanding complex physiologies encountered in the critical care setting.
