Double Outlet Right Ventricle = The aorta rises from the right ventricle (the chamber of the heart that pumps blood to the lungs), instead of from the left ventricle (the pumping chamber to the body).
Atrial Septal Defect (ASD) = The wall that separates the upper heart chambers (atria) does not close completely.
Ventricular Septal Defect (VSD) = One or more holes in the wall that separates the right and left ventricles of the heart. This is the most common of congenital heart defects present at birth.
Transposition of the Great Arteries = The two major vessels that carry blood away from the heart -- the aorta and the pulmonary artery -- are switched (transposed).
Coarctation of the Aorta = A narrowing of part of the aorta (the major artery leading out of the heart).
