Understanding the uterine artery Doppler waveform and its relationship to spiral artery remodelling.

Placenta 2021 Feb 16;105:78-84. Epub 2021 Jan 16.

Department of Physiology, Development and Neuroscience, University of Cambridge, Cambridge, UK; Centre for Trophoblast Research, University of Cambridge, Cambridge, UK. Electronic address:

Analysis of the uterine artery (UtA) Doppler waveform is frequently used in high-risk pregnancies to assess the likelihood of adverse pregnancy outcomes, including preeclampsia and fetal growth restriction. Whilst abnormal UtA waveforms at 18-20 weeks are associated with adverse outcomes, the underlying cause of these waveform changes remains unknown. Current evidence suggests the long-held dogma that the UtA waveform is merely a reflection of trophoblast-induced spiral artery remodelling is incorrect. Read More

Comput Methods Programs Biomed 2021 Jan 22;198:105768. Epub 2020 Oct 22.

Dalton Cardiovascular Research Center, University of Missouri, USA. Electronic address:

Background And Objective: The accuracy of systolic and diastolic blood pressure levels from oscillometric devices is difficult to assess for patients with atrial fibrillation and arterial stiffness; in such cases, changes in these levels from heartbeat to heartbeat can only be known if the actual total waveform during a test can be observed. Variation in these levels affects the accuracy of the algorithms in oscillometric devices where precision is of paramount importance according to the American College of Cardiology and the American Heart Association. Recently issued guidelines lowered the definition of high blood pressure; approximately three-quarters of men over 65 years of age meet the criterion and are diagnosed as hypertensive. Read More

Prospective longitudinal cohort study of uterine arteries Doppler in singleton pregnancies obtained by IVF/ICSI with oocyte donation or natural conception.

Hum Reprod 2020 11;35(11):2428-2438

Obstetrics and Gynecology Department, IRCCS San Raffaele Hospital, Vita-Salute University, Milan, Italy.

Study Question: Do uterine arteries Doppler studies show different pulsatility index (UtA-PI) measurements in IVF/ICSI pregnancies with oocyte donation (OD) as compared to natural conceptions?

Summary Answer: In IVF/ICSI pregnancies with OD, UtA-PI is reduced by an average of about 40% as compared to pregnancies with natural conception.

What Is Known Already: OD pregnancies present worse pregnancy outcomes as compared to natural conception, particularly for increased incidence of pre-eclampsia (PE). Recent evidence shows that IVF/ICSI pregnancies with frozen blastocyst transfer also present higher prevalence of PE and 15% lower UtA-PI as compared to pregnancies after fresh blastocyst transfers.

Peroxisome proliferator-activated receptor gamma blunts endothelin-1-mediated contraction of the uterine artery in a murine model of high-altitude pregnancy.

FASEB J 2020 03 23;34(3):4283-4292. Epub 2020 Jan 23.

Department of Medicine, University of Colorado School of Medicine, Aurora, CO, USA.

The environmental hypoxia of high altitude (HA) increases the incidence of intrauterine growth restriction (IUGR) approximately threefold. The peroxisome proliferator-activated receptor γ (PPAR-γ), a ligand-activated nuclear receptor that promotes vasorelaxation by increasing nitric oxide and downregulating endothelin-1 (ET-1) production, has been implicated in IUGR. Based on our prior work indicating that pharmacologic activation of the PPARγ pathway protects against hypoxia-associated IUGR, we used an experimental murine model to determine whether such effects may be attributed to vasodilatory effects in the uteroplacental circulation.
