In contrast to adult patients with acquired heart disease, abnormalities of the right ventricle (RV) are ubiquitous in children and adults with congenital heart disease (CHD). The RV is exposed to volume overload in shunt lesions (eg, atrial septal defect, anomalous pulmonary venous connections), as well as congenital or acquired tricuspid and pulmonary valve regurgitation. RV pressure overload characterizes numerous congenital anomalies, including pulmonary valve stenosis or atresia, large ventricular septal defect, single ventricle, tetralogy of Fallot (TOF), truncus arteriosus, and transposition of the great arteries, to name a few. Importantly, many surgical and transcatheter treatments of CHD result in persistent or acquired volume and pressure overload of the RV. In some patients with CHD, the RV functions as the systemic ventricle (eg, palliated hypoplastic left heart syndrome, physiologically corrected transposition of the great arteries, and D-loop transposition of the great arteries after atrial switch procedure). Furthermore, exposure to cyanosis and surgical procedures in the RV often leads to myocardial abnormalities, including scar tissue and diffuse fibrosis. Response by Yeh and Foster see p 197
