The epidemiology of congenital heart disease (CHD) has changed in the past 50 years as a result of an increase in the prevalence and survival rate of CHD. In particular, mortality in patients with CHD has changed dramatically since the latter half of the twentieth century as a result of more timely diagnosis and the development of interventions for CHD that have prolonged life. As patients with CHD age, the disease burden shifts away from the heart and towards acquired cardiovascular and systemic complications. The societal costs of CHD are high, not just in terms of health-care utilization but also with regards to quality of life. Lifespan disease trajectories for populations with a high disease burden that is measured over prolonged time periods are becoming increasingly important to define long-term outcomes that can be improved. Quality improvement initiatives, including advanced physician training for adult CHD in the past 10 years, have begun to improve disease outcomes. As we seek to transform lifespan into healthspan, research efforts need to incorporate big data to allow high-value, patient-centred and artificial intelligence-enabled delivery of care. Such efforts will facilitate improved access to health care in remote areas and inform the horizontal integration of services needed to manage CHD for the prolonged duration of survival among adult patients.
Measurable changes in the prevalence of congenital heart disease (CHD) in the past decades are the result of evolving trends in birth prevalence and survival of patients over time.
Changes in birth prevalence over time and by region are, at least in part, attributable to variations in the availability of diagnostic tools and ascertainment.
Despite regional variations, the survival rates of patients with CHD have improved globally as evidenced by an increasing median age of CHD populations.
With prolonged survival among patients with CHD, the disease burden is shifting away from the heart and towards acquired cardiovascular and systemic complications throughout the lifespan.
Lifespan disease trajectories for CHD populations with a high disease burden measured over prolonged time windows are becoming increasingly important to define long-term outcomes that can be improved.
Strategically deployed, high-quality care will facilitate the integration of services that are needed to manage CHD and related comorbidities for the duration of the patient’s life.
