Overview
Transposition of the great arteries (TGA) is one of the most common cyanotic congenital heart defects present in the first 24 hours of life.
Epidemiology and Demographics
- Heart defects are the most common birth defect, occurring in approximately 1% of live births.
- Transposition of the great arteries TGA is one of the most common cyanotic congenital heart defects present in the first 24 hours of life.
- Approximately one million people worldwide are currently living with a CHD.
- TGA represents 5-7% of all CHD with an incidence at birth of 20-30 in 100000 live births and almost 20 percent of all cyanotic CHD defects.
- TGA is more common in infants of diabetic mothers.
- Boys outnumber girls with an approximate ratio of 2:1.
- Without treatment, 30% of infants die within the first week of life, 50% will die in the first month, 70% will die in the first 6 months and 90% of infants will die before the end of the first year.
- Having a child with a CHD increases an individual’s chances of having another child with a CHD from 1% to 3%. Subsequent children born with a CHD increase that individual’s chances further.
