Comparison of visual estimation of ventricular systolic function with quantitative echocardiographic markers in newborn infants

Background

Neonatologist-performed echocardiography (NPE) is increasingly practiced. NPE operators typically use visual estimation of systolic function and, if indicated, confirm function using quantitative echocardiographic markers. This exploratory study aims to compare the concordance between qualitative and quantitative echocardiographic markers among NPE and non-NPE operators.
