A congenital diaphragmatic hernia occurs when the diaphragm -- the muscle that separates the chest from the abdomen -- fails to fuse completely and leaves a space for the stomach, intestines, and liver to move into the chest. This can keep the lungs from growing properly. Small and underdeveloped lungs, referred to as pulmonary hypoplasia, can result in significant breathing problems including pulmonary hypertension (high blood pressure in the lungs).
