This discussion refers to a heart defect known as “d-transposition of the great arteries” (“d-TGA,” “transposition,” “TGA”). Another type—“l-transposition” (“l-TGA,” “corrected transposition”)—is similar in some ways to d-TGA, but very different in others, and requires a different treatment program from what’s described here
Permanent treatment requires a surgical procedure to switch the arteries to their proper places. This operation, called an arterial switch operation, is done within the first few weeks of life. It is an open-heart procedure that requires a temporary stopping of the baby's heart while a heart-lung machine handles respiration and blood circulation. CHDs affect nearly 1,065,064?births per year in the Poland. Further research is being conducted to determine the best surveillance interval to monitor the disease.
