Longitudinal hemodynamic evaluation of uncomplicated twin pregnancies according to chorionicity: physiological cardiovascular dysfunction in monochorionic twin pregnancy
CONCLUSIONS: Maternal cardiovascular function undergoes significant changes during an uncomplicated twin pregnancy and chorionicity influences maternal hemodynamics. In both twin pregnancies the hemodynamic changes are detected as early as the first trimester. In DC twin pregnancies the maternal hemodynamics remain stable during the rest of pregnancy. On the contrary, in MC twin pregnancies the rise in maternal CO continues in the second trimester to sustain the higher placental growth. There is a subsequent cross-over with a reduction in cardiovascular performance during the third trimester. This article is protected by c...

Vascular phenotype at 35-37  weeks' gestation in women with gestational diabetes mellitus
CONCLUSION: Women with GDM have evidence of early vascular disease and this may contribute to their long-term cardiovascular risk. This article is protected by copyright. All rights reserved.PMID:36173400 | DOI:10.1002/uog.26077

Impact of maternal height, booking weight and gestational weight gain on cardiac adaptation in pregnancy
CONCLUSIONS: Women with greater booking weight have a pathological hemodynamic profile with high CO, PVR and MAP compared to those of lesser weight. Height is the main determinant of CO, SV, HR and PVR; weight is the main determinant of MAP and gestational weight gain is the second most important influencer for SV and PVR.

Maternal echocardiographic changes in twin pregnancies with and without pre-eclampsia
CONCLUSIONS: The maternal cardiovascular system is severely altered by a twin pregnancy with and without HPD. Despite a low total vascular resistance, cardiac changes in normotensive twins are comparable with those seen in singletons complicated by HDP reflecting the high cardiovascular demand imposed by a twin pregnancy.

The effect of maternal age on cardiac adaptation in pregnancy.
CONCLUSIONS: Age-specific differences in maternal hemodynamic adaptation do not explain the differences in birth of SGA neonates between age groups. This article is protected by copyright. All rights reserved. PMID: 33592675 [PubMed - as supplied by publisher]

Fetal cerebral vascular impedance is abnormal in left congenital diaphragmatic hernia.
CONCLUSION: MCA PI values are significantly lower in L-CDH fetuses as compared to controls and a lower LVCO was correlated with lower MCA vascular impedance. The neurodevelopmental effect of changes in MCA PI in response to decreased LVCO are unknown, although all survivors that underwent testing in this cohort scored in the normal range.

Improved detection of coarctation of the aorta using speckle tracking analysis of the fetal heart using the last examination prior to delivery.
CONCLUSIONS: Speckle tracking analysis of multiple ventricular measurements may be helpful to separate fetuses that are suspected to have CoA prenatally from those who do not. This article is protected by copyright. All rights reserved. PMID: 32022339 [PubMed - as supplied by publisher]

Maternal cardiovascular function and risk of intrapartum fetal compromise in women undergoing induction of labor: a pilot study.
CONCLUSION: In this pilot study, we demonstrated that pre-labour maternal cardiovascular assessment in women undergoing IOL could be useful for assessing the risk of intrapartum fetal compromise necessitating operative delivery. The addition of SV, SVR and SVRI significantly improved the predictive accuracy of the baseline antenatal model. This article is protected by copyright. All rights reserved.

The effect of race on longitudinal maternal central hemodynamics.
CONCLUSION: There are race-specific differences in maternal cardiac adaptation in pregnancy. White women have the most favourable cardiac adaptation by increasing SV and HR, achieving the highest CO and lowest PVR. In contrast, Black and Asian, compared to White women, have lower CO and higher PVR, increasing their CO through a rise in HR due to a declining or static SV. This article is protected by copyright.

Effect of sildenafil on maternal hemodynamics in pregnancies complicated by severe early-onset fetal growth restriction: planned subgroup analysis from a multicenter randomized placebo-controlled double-blind trial.
CONCLUSIONS: Sildenafil in a dose of 25 mg three times daily increases HR, reduces BP and reduces arterial stiffness in pregnancies complicated by FGR. These changes are modest, consistent with the anticipated vasodilatory effect and their clinical impact on the mother and baby, in both the short- and long-term, remains uncertain.

Are maternal hemodynamic indices markers of fetal growth restriction in pregnancies with a small-for-gestational-age fetus?
CONCLUSION: Pregnancies complicated by FGR present with worse maternal hemodynamic function, as evidenced by lower heart rate and cardiac output as well as higher mean arterial pressure, systemic vascular resistance and uterine artery resistance. Pregnancies resulting in a SGA neonate, without evidence of FGR have normal maternal hemodynamic function. Maternal hemodynamic indices may be of value in distinguishing FGR from SGA pregnancies.
