Synonyms
- Transposition of great arteries (TGA)
- D-transposition
- Dextrotransposition
- Congenitally corrected transposition of great arteries (CTGA)
- L-transposition
- Ventricular inversion
- Levotransposition
- Transposition of great arteries (TGA)
Definitions
- TGA: Ventriculoarterial (VA) discordance
- Aorta arises from right ventricle (RV)
- Pulmonary artery (PA) arises from left ventricle (LV)
- Further distinguished by presence/absence of ventricular septal defect (VSD)
- CTGA: Atrioventricular (AV) and VA discordance
- Right atrium → LV → PA
- Left atrium → RV → aorta
- TGA: Ventriculoarterial (VA) discordance
