The research proposed here is motivated by the need to support pediatric cardiologists in making image-based decisions in the assessment and management of congenital heart disease (CHD). In marked contrast to adult cardiology, which deals almost exclusively with the left ventricle (LV), the function of the RV is associated with a number of life-threatening conditions in pediatrics. These defects include Hypoplastic Left Heart Syndrome (HLHS), Congenitally Corrected Transposition of Great Arteries, Post operative Tetralogy of Fallot, and Double Outlet Right Ventricle.
