Complex congenital cardiovascular disease rarely causes symptoms in the fetus but within hours or days after birth may cause the newborn infant to become critically ill. Specific defects lead to predictable cardiac and vascular alterations, and knowledge of such associations assists the clinician in the evaluation, diagnosis, and treatment of the critically ill newborn. This chapter reviews important physiologic aspects of the fetal circulation, how the fetal circulation can be monitored for hemodynamic stability, and the changes in circulatory physiology that occur at birth.
