Automated quantitative evaluation of atrioventricular annular plane systolic excursion in human fetuses

CONCLUSIONS: This study showed that fetal AVPD can be measured integrating cTDI velocities over several cardiac cycles using an automated analysis software. Potentially, automated analysis of AVPD could help gathering larger data sets to facilitate the use as machine-learning models to study fetal cardiac function. The gestational age associated increase in AVPD is most likely a result of increasing cardiac size as the AVPD normalized by cardiac size did not change significantly between 18-42 weeks. A decrease was seen in TAPSE and SAPSE in IUGR fetuses, but not when corrected for cardiac size. This article is protected by copyright. All rights reserved.PMID:34096674 | DOI:10.1002/uog.23703
