The objectives of this review are to discuss the global epidemiology of cardiovascular disease, emphasizing congenital heart disease; to discuss the concept of epidemiologic transition and its role in studying the evolving epidemiology of disease; and to assess and address the global burden of congenital heart disease including its prevention and treatment. ⋯ Despite impressive reductions in mortality from congenital and acquired cardiovascular disease in high-income countries, these reductions have not been observed on a global scale. It will be necessary to continue our attempts to extend rational programs of care to middle- and low-income countries based on community empowerment, economics, and population health. The specialist in pediatric cardiac critical care can be a central driver of these programs.

To review the clinical classification, diagnosis, and pathophysiology of pulmonary hypertension in children, emphasizing the role of right ventricular function, ventricular interaction, and congenital heart disease in the evolution and progression of disease, as well as management strategies and therapeutic options. ⋯ Critically ill children with pulmonary hypertension associated with congenital heart disease are a high-risk population. Congenital cardiac defects resulting in either increased pulmonary blood flow or impaired pulmonary venous drainage predispose patients to developing structural and functional aberrations of the pulmonary vasculature. Mortality from pulmonary hypertension is most directly related to right ventricular failure.

The purpose of this chapter is to outline the causes, physiology, pathophysiology, and management strategies for hydrostatic and permeability pulmonary edema and hypoxic respiratory failure. ⋯ The pulmonary parenchyma and vasculature are at high risk in conditions where injury occurs to the lung and or heart. A targeted approach that uses strategies that optimize the particular pathophysiology of the parenchyma and vasculature is required.

ReviewFluid Management: Pharmacologic and Renal Replacement Therapies.
Focusing on critically ill children with cardiac disease, we will review common causes of fluid perturbations, clinical recognition, and strategies to minimize and treat fluid-related complications. ⋯ Meticulous fluid management is vital in critically ill children with cardiac disease. Fluid therapy is important to maintain adequate blood volume and perfusion pressure in order to support cardiac output, tissue perfusion, and oxygen delivery. However, fluid overload and acute kidney injury are common and are associated with increased morbidity and mortality. Understanding the etiologies for disturbances in volume status and the pathophysiology surrounding those conditions is crucial for providing optimal care.

ReviewExtracorporeal Membrane Oxygenation for Cardiac Indications in Children.
The objectives of this review are to discuss the use of extracorporeal membrane oxygenation following surgery for congenital heart disease, myocarditis and as a bridge to cardiac transplantation. In addition, the latest in circuit equipment, the management of anticoagulation and blood transfusions, and short- and long-term outcomes are reviewed. ⋯ The use of extracorporeal membrane oxygenation to support children with heart disease is increasing. There is wide variability in the use and management of extracorporeal membrane oxygenation between centers. Many areas of extracorporeal membrane oxygenation management warrant additional research to inform clinical practice and improve patient outcomes, including the use of extracorporeal membrane oxygenation in patients undergoing single ventricle palliation, optimizing strategies for monitoring and titrating anticoagulation therapies, and efforts directed at minimizing the risk of neurologic injury.
