Background: COVID-19 is a viral infectious disease leading to a spectrum of clinical
complications, especially cardiovascular. Evidence shows that this infection can potentially …

Abstract Background The Doppler effect has allowed the characterization of several vessels
in maternal-fetal circulation that have been used for practical purposes. Our review of the …

Objective: To determine whether the acceleration/ejection time ratio of the fetal main
pulmonary artery Doppler waveform (PATET) can accurately predict the results of fetal lung …

Objective To describe changes in the Doppler waveforms of the fetal main pulmonary artery
(MPA) throughout gestation and to assess their predictive value of neonatal respiratory …

Objective This study investigates whether fetal pulmonary artery Doppler waveforms can
predict the subsequent development of respiratory distress syndrome (RDS). Study Design …

Objective: We aimed with this study to evaluate the role of pulmonary artery acceleration
time to ejection time ratio (PATET) in the prediction of respiratory distress syndrome (RDS) in …

Objective: To study whether fetal main pulmonary artery (MPA) Doppler indices can predict
the development of neonatal respiratory distress syndrome (RDS). Study Design: This …

Background: Prenatal evaluation of fetal lung maturity (FLM) is a challenge, and an effective
non-invasive method for prenatal assessment of FLM is needed. The study aimed to …

Objective: To determine the prognostic accuracy of the fetal pulmonary artery acceleration
time/ejection time (PATET) for the prediction of neonatal respiratory complications (NRCs) in …

Purpose To determine the effect of SARS‐CoV‐2 infection on the fetal pulmonary system
using the acceleration time (AT), ejection time (ET), and acceleration/ejection time ratio …
