Abstract:
Objective To obtain measurements of fetal four-chamber view and left and right ventricular shapes using two-dimensional speckle tracking,and to explore the clinical quantification of cardiac shape remodeling in small for gestational age(SGA)fetuses.Methods In this study,we prospectively collected data on singleton pregnancies from 28 to 39 weeks that were established in the archives of Obstetrics and Gynecology Hospital,Fudan University from May 2020 to Jul 2021.Fetuses eligible for inclusion criteria were randomly matched according to the ratio of estimated fetal weight(EFW)≥10th percentile(P10)∶EFWP90 in the apical segments of the left ventricle was greater in normal UAPI fetuses than that in low-risk fetuses(24.2%vs.14.3%,P=0.005);the SI of left ventricle in UAPI-normal SGA fetuses was greater in segments S1 to S22 than that of right ventricle with statistically significant difference(all P<0.05),while no significant difference was found between the SI of left and right ventricles in segments S23 and S24.Conclusion About one-fourth of SGA fetuses with normal UAPI have abnormally increased apical segments of the left ventricular SI,suggesting that cardiac remodeling with a predominantly"elongated"apical segments of the left ventricle precedes Doppler anomalies.
