I have decided to add this page after receiving a few emails from indivuals on Transposition most saying that they have a friend or relative whom are adults and doing fine with thier Transposition, and some whom have mentioned that their child was not diagnoised Until 6 months to 1 year. In addition to D-Transposition , Jacob had dextracardia, L-Looped ventricals double-outlet right ventrical, pulmonary atresia,large ventrical septal defect, unrestricted ASD, and patent ductus arteriosius. The type of survival depends a great deal on the type of Transposition , in addition to other factors for example health,physicians,other defects, and so forth. No Individual is the same and treatments may vary. Transposition is a very serious form of heart disease, In which the two main valves to the heart are switched and a surgery is usually performed at Birth for the child to survive. Some forms of Transposition might include L-Transposition of the Great Vessels ,orD-Transposition of the Great Vessels. In L Transposition , it may not show signs until adulthood, In D Transposition,or complete, the infant begins to show signs within the first 48 hours usually. Below are some links to learn more about Transposition of the Great Vessels. Heart Disease Online Lucile Packard Children's Hospital
