Over the past five decades, there have been multiple advances in the treatment of congenital heart defects, resulting in an increasing population of adults living with congenital heart disease (CHD). Despite improved survival, CHD patients often have residual haemodynamic sequelae and limited physiologic reserve and are at increased risk for acute decompensation with occurrence of arrhythmias, heart failure, and other medical conditions. Comorbidities occur more frequently and at an earlier age in CHD patients than in the general population. The management of the critically ill CHD patient requires an understanding of the unique aspects of congenital cardiac physiology as well as the recognition of other organ systems that may be involved. Certain patients may be candidates for mechanical circulatory support, and goals of care should be established with advanced care planning.
