Abstract
The primary goal of targeted neonatal echocardiography (TNE) is to enhance noninvasive hemodynamic assessment, guide therapeutic interventions, and ultimately improve the outcomes of newborns with hemodynamic instability. Abnormal postnatal hemodynamics are commonly seen when the transitional circulation is complicated by structural heart disease, prematurity, perinatal asphyxia, sepsis, hemorrhage, or respiratory failure. The use of echocardiography in augmenting diagnosis and tailoring therapy has become standard of care in neonatal intensive care units. Comprehensive TNE evaluation should include assessment of ventricular systolic and diastolic performance, right and left heart volume/pressure loading, right ventricle and left ventricle outputs, pulmonary arterial hypertension and pulmonary vascular resistance, and shunt physiology. The persistent ductus arteriosus flow velocity‐derived gradient during systole provides information about the relationship between the systemic arterial pressure and the pulmonary arterial pressure. Congenital diaphragmatic hernia is associated with lung hypoplasia, abnormal lung parenchyma, and abnormal pulmonary vasculature. Persistent ductus arteriosus remains the most common cardiovascular condition afflicting neonates.
