Objective: To evaluate the usefulness of the estimation of fetal pulmonary artery pressure obtained by doppler ultrasound as an indicator of fetal maturity and its correlation with neonatal outcomes in a group of patients attending the delivery room area of the Hospital Central de San Cristobal, between March and July 2023. Methods: This is an observational, descriptive, correlational study. The sample consisted of 90 women (90 fetuses) with a single pregnancy between 34 and 40 weeks of gestation. Results: From the doppler variables analyzed, it was evidenced that the fetal pulmonary artery pressure decreased significantly (p < 0.001) with advancing gestational age. It was determined that there is a significant inverse association between fetal pulmonary artery pressure and fetal maturity (p < 0.001), such that the lower the fetal pulmonary artery pressure value, the higher the percentage of fetal maturity. A fetal pulmonary artery pressure cut-off point located at 55.9 mm Hg jointly determined the highest sensitivity and specificity f or t he d iagnosis o f f etal l ung maturity, i ts s ensitivity being 93.75% and specificity being 80.77%. With a positive predictive value of 92.31% and a negative predictive value of 84%. Conclusion: The estimation of fetal pulmonary artery pressure obtained by doppler ultrasound is useful as an indicator of fetal maturity. Keywords: Doppler, Fetal pulmonary artery pressure, Fetal maturity, Cut-off point

“…In 2016, Cowie et al also studied cardiac surgical patients and found that PAT<107 msec predicted PAH 21 . More recently, Zhan et al utilized PAT to classify PAH severity (mild 70–90 msec, medium 50–70 msec, and severe <50 msec) 22 . Interestingly, adults exposed to hyperoxia (100%O 2 ) had modestly lengthened PAT, whereas hypoxia (17%O 2 ) had minimal effect 23 .…”

PATET ratio by Doppler echocardiography: noninvasive detection of pediatric pulmonary arterial hypertension

et al. 2021

Pulmonary artery acceleration time (PAT) and PAT: ejection time (PATET) ratio are echocardiographic measurements of pulmonary arterial hypertension (PAH). These non-invasive quantitative measurements are ideal to follow longitudinally through the clinical course of PAH, especially as it relates to need for and/or response to treatment. This review article focuses on the current literature of PATET measurement for infants and children as it relates to shortening of the PATET ratio in PAH. At the same time, further development of PATET as an outcome measure for PAH in pre-clinical models, particularly mice, such that the field can move forward to human clinical studies that are both safe and effective. Here we present what is known about PATET in infants and children and discuss what is known in pre-clinical models with particular emphasis on neonatal mouse models. In both animal models and human disease, PATET allows for longitudinal measurements in the same individual, leading to more precise determinations of disease/model progression and/or response to therapy.
