Conclusion

Over the three periods in our study, the left ventricular outflow tract is mainly carried out. The quality scores remained globally stable since the updating of the CNEOF recommendations in 2016, despite the introduction in 2019 of quality criteria in an attempt to improve practices related to obtaining LVOT images. No significant change in practices was noted in the first quarter of 2020, following the introduction of the LVOT quality criteria. Finally, the main limiting cause of the lack of improvement in cardiac screening is probably human, due to possible lack of interest on the part of operators, and/or a lack of appropriation for the quality criteria, and/or errors in the choice of quality criteria proposed (too complex).
Analysis of the foetal heart remains challenging, mainly due to its complex anatomy, the small size of the areas studied, heart movements, involuntary foetal movements, and the lack of expertise in foetal echocardiography among some sonographers. Therefore, the use of new Artificial Intelligence-supported technologies aimed at making screening echocardiography practices safer seems likely to be the next step towards precision medicine in the future (25)(31).
