The Role of Catheter-Based and Surgical Treatments in Patients With Congenital Heart Disease and Pulmonary Hypertension

This manuscript is intended to provide a brief overview of the indications for and outcomes of surgical and transcatheter interventions for congenital heart disease and pulmonary hypertension (PH). Pulmonary hypertension is frequently encountered in children and adults with congenital heart disease and is most commonly related to large “central” shunts, ie, those occurring at the ventricular or great arterial level (Figure 1). If uncorrected early in infancy or childhood, large central shunts result in increased pulmonary blood flow, left heart volume overload, PH, and heart failure. If the child survives this initial period of volume overload and heart failure, they will very likely develop effacement of the normal pulmonary arterial architecture and severe elevations in pulmonary arterial resistance, eventually resulting in cyanosis and Eisenmenger syndrome.1
