Characterizing fetoplacental response to acute maternal hyperoxygenation in suspected coarctation of aorta using fetal cardiac <scp>MRI</scp>
AMH leads to a significant reduction in cerebral blood flow in fetuses with suspected CoA, which is the primary driver of changes in flow at the aortic isthmus. Future studies should consider the effects of maternal oxygen on the entirety of fetoplacental circulation, particularly for cases in which chronic maternal hyperoxygenation administration is being considered. © 2025 The Author(s).
