What is congenital diaphragmatic hernia (CDH)?

Congenital diaphragmatic hernia, or CDH, is one of the most common birth defects, affecting about one in 3000-4000 newborns today. CDH occurs when the diaphragm develops abnormally during gestation, creating a defect, or hole, through which organs such as the intestines migrate into the chest.
