CHD incidence in offspring of mothers with non-inherited and non-syndromic forms of CHD: a single-centre retrospective cohort study

The incidence of CHD among offspring of mothers with CHD in our cohort was higher than the general population; however, the majority of defects were non-critical and did not require early intervention. These findings offer important context for prenatal counselling and tailored fetal/neonatal echocardiography screening in this high-risk population.
