简要总结
Determine 1) the impact of abnormal fetal cerebrovascular physiology with neurodevelopmental delay (ND) outcomes and 2) how this relationship is modified by patient and environmental factors such as chronic congenital heart disease (CCHD) lesion, maternal-fetal environment, and social determinants of heath (SDOH) in a diverse population using a multicenter design.
Pregnant women will be approached during one of their fetal cardiology clinic visits.
详细描述
Aim 1:
Determine the association of baseline cerebrovascular resistance and reactivity and pre-operative neurobehavior in neonates with complex congenital heart disease (CCHD).
Exposures: The baseline middle cerebral artery pulsatility index (MCA-PI) and change in MCA-PI.
Analyses: Our principal analyses for Aim 1 will use separate linear regression models to relate the Neonatal Intensive Care Unit Network Neurobehavioral Scale (NNNS) attention score to 1) the baseline MCA-PI while controlling for maternal age, infant sex, race/ethnicity, and SDOH measures (maternal education, socioeconomic status (SES), insurance status), and clinical site, and 2) the change in MCA-PI adjusted for baseline MCA-PI while controlling for the same set of covariates. If the NNNS attention score distribution is skewed, we will consider transformations so that model residual plots achieve approximate normality. The covariates in the above regression analyses exclude factors that may potentially lie on the causal pathway from the MCA-PI to the attention score to avoid risk of over adjustment. In secondary analyses, 2 regression analyses will be repeated after additional adjustment for the maternal-fetal environment indicator(s), CCHD category, and age at NNNS evaluation. As a secondary analysis, we will evaluate the interaction between baseline MCA-PI and change in MCA-PI. For this analysis, we will consider dichotomizing baseline MCA-PI to facilitate interpretation of the interaction effect.

研究组 & 干预措施
Single Arm
Maternal Hyperoxia (MH) will be administered to pregnant patients after their standard of care fetal echocardiogram has been performed at their scheduled fetal cardiology visit at ³28 weeks gestation. The evaluation at ³28 weeks was chosen since gestational age impacts both the cardiovascular and cerebrovascular response to MH.31 The evaluation will extend the duration of the visit by approximately 30 minutes but additional evaluations or visits for the study will not be required.
