Left ventricular flow dynamics in preterm infants assessed with high frame rate echocardiography with blood speckle tracking

In this study, we explored a subgroup of newborns with high risk of cardiac failure during their intensive care stay, the very preterm infant. We present reference values for blood speckle-tracking-derived measures of cardiac efficiency. This data can assist in the development of further clinical applications for echo blood speckle tracking in preterm infants, such as predicting disease progression, monitoring treatments, and early diagnosis of adverse left ventricular (LV) remodeling.
