Congenital heart disease can predispose individuals to pulmonary vascular remodeling as a result of the abnormality in pulmonary blood flow and pressure that accompanies the specific congenital defect being considered. Pulmonary arterial hypertension associated with congenital heart defects is an important determinant of functional capacity and survival, especially when the Eisenmenger's state of reversed shunt is present. The likelihood of right ventricular dysfunction and failure increases with the degree of pulmonary artery pressure. Thus, the aim of disease management in this patient population should be to prevent or improve right heart failure. Current therapies that modify the progression of pulmonary vascular disease-including endothelin-1 receptor antagonists, phosphodiesterase-5 inhibitors, and prostanoids-should be considered carefully in patients with congenital heart disease-associated pulmonary hypertension. The risks and benefits of altering the balance of pulmonary vascular resistance to systemic vascular resistance must be weighed for each patient.

Congenital heart disease (CHD) is a common structural defect of the heart or major blood vessels. Patients with adult congenital heart disease (ACHD) have medical needs that are distinct from those of pediatric patients with CHD, and the transition into adult health care is important for management of the patient with ACHD. A large proportion of patients with CHD develop diseases and complications associated with the long-term stress of intracardiac shunts. Pulmonary arterial hypertension (PAH) is a significant complication of some CHD lesions. The treatment of these patients remains challenging due to their combined heart and lung disease, and multidisciplinary care is ofen necessitated for a variety of secondary conditions. A number of treatment options are available for the management of PAH associated with CHD, including prostanoids, phosphodiesterase type-5 inhibitors, and endothelin receptor antagonists. This article discusses the diagnosis and management of such ACHD patients with PAH.
