Digital profile of children’s hearts: automated echocardiogram strain analysis facilitates earlier detection of cardiac dysfunction
Authors' conclusion
Leveraging a large-scale paediatric dataset, Motion-Echo provided a reliable and generalizable framework for myocardial strain analysis, demonstrating potential to facilitate earlier detection of cardiac dysfunction and generate digital cardiac function profiles of children.
