Do novel quantitative echocardiography methods improve the functional assessment of the newborn heart compared to conventional methods?
Novel echocardiographic techniques like tissue Doppler and speckle tracking provide advanced quantitative assessment of neonatal cardiac function, aiding in the management of normal and maladaptive responses.
May refine neonatal cardiac assessment beyond conventional echo; leaves open prospective outcome validation before routine use.
Echocardiography in the neonatal intensive care unit has led to improvements in our ability to assess the neonatal heart in health and disease. Advances in neonatal cardiac imaging have provided the capability to obtain quantitative information that often supersedes the qualitative information provided by conventional methods. Novel quantitative measures of function include the assessment of the velocity of muscle tissue movement during systole and diastole using tissue Doppler velocity imaging, and evaluation of deformation and rotational characteristics of the myocardium utilizing speckle tracking echocardiography or tissue Doppler-derived strain imaging. A comprehensive understanding of these novel functional modalities, their predictive value, and limitations can greatly assist in managing both the normal and maladaptive responses in the newborn period. This article discusses the novel and emerging methods for assessment of left and right heart function in the neonatal population.
