Is transposition of the great vessels the same as transposition of the great arteries?
Beside this, is transposition of the great arteries hereditary?
In most cases of TGA, only one family member is affected. The findings of some studies have suggested that TGA is a sporadic defect, while other studies have found that the risk for TGA to occur in a sibling of an affected individual is in the range of 0.2% - 1.4%.
- Arterial switch operation. This is the most common surgery used to correct transposition of the great arteries. Surgeons usually perform this surgery within the first month of life.
- Atrial switch operation. In this surgery, the surgeon makes a tunnel (baffle) between the heart's two upper chambers (atria).
Furthermore, how rare is transposition of the great arteries?
Transposition of the great arteries (TGA), also referred to as complete transposition, is a congenital cardiac malformation characterised by atrioventricular concordance and ventriculoarterial (VA) discordance. The incidence is estimated at 1 in 3,500–5,000 live births, with a male-to-female ratio 1.5 to 3.2:1.
Untreated, over 50 percent of infants with transposition will die in the first month of life, 90 percent in the first year. When a newborn with significant cyanosis is first seen, they are often placed in supplemental oxygen.
