Congenital heart disease (CHD) is the most common anatomical malformation occurring live-born infants and an increasing cause of morbidity and mortality across the lifespan and throughout the world. Population-based observations have long described associations between maternal cardiometabolic disorders and the risk of CHD in the offspring. Here we review the epidemiological evidence and clinical observations relating maternal obesity and diabetes mellitus to the risk of CHD offspring with particular attention to mechanistic models of maternal-fetal risk transmission and first trimester disturbances of fetal cardiac development. A deeper understanding of maternal risk factors holds the potential to improve both prenatal detection of CHD by identifying at-risk pregnancies, along with primary prevention of disease by improving preconception and prenatal treatment of at-risk mothers.
