Description
Summary:Abstract Funding Acknowledgements Type of funding sources: None. Background The analysis of systolic-diastolic function by two-dimensional ultrasound speckle-tracking strain (2DSTE) in the paediatric population is becoming progressively more available, its use can be helpful in the diagnosis of subclinical pathology in paediatric disease, both in acquired cardiovascular pathology, congenital heart disease and especially in cardio-oncology(1-4). For this purpose,  a reliable, reproducible, and easy-to-use technique is required(5). Purpose To assess the feasibility and reproducibility of the strain using the software of newest software based on artificial intelligence, of one of the widely available companies in our environment. Methods A cross-sectional study was carried out in a population in Andalusia, Spain. Of 265 children who agreed to participate, 156 healthy children aged 6-17 years were selected by excluding congenital or acquired heart disease. Analysis using the new auto-strain software for the left ventricle, right ventricle, and left atrium. Feasibility and gender differences were assessed. As well as inter- and Inter-observer variability. Results  The feasibility of the auto-strain measurement ranged from 94.2% for left ventricular global longitudinal strain (LVGLS) to 98.1% for other chamber strain parameters. No differences were found in matters of gender (Table 1). Excellent intra- and interobserver reproducibility was found for the measurement of right and left ventricular strain (intraclass correlation coefficients ranged between 0.88 and 0.98, respectively). (Table 2) Conclusions  The strain analysis by auto-strain was both highly feasible and reproducible using this new software. Abstract Figure.  Abstract Figure.
