“…A recent prospective cohort study found that pregnant women who were obese demonstrated impaired myocardial function, measured by end-systolic wall stress, left ventricle cardiac index, and left ventricle mass index, compared with women who were not obese. 57 These researchers also showed that women with obesity had higher blood pressure readings, systemic vascular resistance measures, and pulsatility index scores than the control group, particularly between 25 and 30 weeks’ gestation. In another study, researchers followed 614 women who initiated recommended aspirin therapy before 16 weeks’ gestation for preeclampsia prevention.…”

“…A TTE study of 69 consecutive healthy women with singleton pregnancies found that pulmonary artery diameter increased in all women from a mean of 20 mm at the end of first trimester to a mean of 22.7 mm at the start of third trimester [50]. The gestational pulmonary artery dilatation resolved postpartum to a mean value of 19.5 mm.…”

Profound physiological changes in the maternal cardiovascular system occur shortly after conception. These changes may impact upon the investigation of healthy and complicated pregnancies. Additionally, concerns regarding fetal exposure to ionising radiation are important considerations in maternal testing. This manuscript reviews the important physiological changes pertinent to the investigation of maternal cardiovascular disease in pregnancy.

“…During normal pregnancy, systemic and pulmonary vessels dilate, resulting in decreased systemic (SVR) and pulmonary vascular resistance (PVR). Study has found that pulmonary artery dilatation in healthy pregnant women is common which is associated with volume overload and low vascular resistance [3].…”

OBJECTIVE To study the association of maternal main pulmonary arterial diameter and neonatal weight of pregnant women with pulmonary arterial hypertension. METHODS We divide patients into 2 group, according to whether the patients with pulmonary arterial hypertension owing to congenital heart disease, or idiopathic pulmonary arterial hypertension. Univariate and multivariate regression analysis were used. After adjusting for various confounding, tangent points were obtained by fitting curves and threshold effect analysis. Finally, we apply a stratified analysis according to New York Heart Association (NYHA) Functional Classification. RESULTS According to the results of multivariate regression analysis, in patients with PAH owing to congenital heart disease, maternal pulmonary arterial diameter was significantly associated with neonatal birth weight, and the regression coefficient was − 37.03, and the 95% confidence interval was − 63.44 to -10.62, P value < 0.001. The result of regression analysis is that when maternal main pulmonary arterial diameter increases by 1 mm, the weight of the newborn will decrease by 37.03g. After stratified analysis, the regression coefficient was − 40.94, and the 95% confidence interval was − 69.68 to -12.20, P value < 0.001. CONCLUSION The maternal main pulmonary artery diameter was significantly correlated with the neonatal birth weight in patients with pulmonary arterial hypertension owing to congenital heart diseases, especially thoses with functional classification I or II.

Pulmonary artery dilatation during normal pregnancy

Abstract: Our study shows pulmonary artery dilatation in healthy pregnant women without any other abnormal echocardiographic findings. These changes in PAD are associated with volume overload and low vascular resistance, and during postpartum they usually subside.
