Transposition of the great arteries

Transposition of the great arteries - Symptoms

Symptoms for babies with Transposition of the great arteries (TGA) usually occur at or soon after birth. Babies that have TGA can have the following symptoms:

  • Breathlessness
  • Palpitations (abnormal sensation of the heart beating)
  • Bluish skin colour (cyanosis)
  • Poor appetite 
  • Weak pulse 

However, severity of the symptoms can vary depending on whether the baby has other congenital heart defects like ventricular septal defect (VSD) or atrial septal defect (ASD), both of which create a pathway for oxygen-rich blood to be pumped to the rest of the body. As such, babies with TGA and VSD or ASD may not have such severe symptoms. 

It is thus possible for people to only discover their TGA condition in adulthood. If you develop breathlessness, palpitations, lower limb swelling, syncope (fainting), giddiness or chest pain you should visit your doctor as soon as possible.
