Key points What's already known about this topic? A disproportionate number of children with cyanotic heart disease suffer from neurodevelopmental (ND) impairment, which is believed to be due in part to abnormal cerebral development in utero. Magnetoencephelography (MEG) is a non‐invasive method for assessing neurodevelopment, but has not been studied in fetuses with congenital heart disease (CHD). What does this study add? In this preliminary study, we showed the feasibility of performing MEG in fetuses with CHD. Fetuses with CHD had different magnetoencephalographic characteristics when compared with matched controls.
