Transposition of the Great Arteries
Echocardiogram done in TGA to evaluate:
- atrioventricular connections
- atrial morphology: determined by venous return and atrial appendage morphology
- ventricular morphology:
- determined by presence of moderator band (right ventricle), trabeculi, valvular morphology, etc.
- seen best in subcostal, parasternal short axis and apical 4 chamber views
- presence of outflow obstruction
Though transthoracic echo can provide valuable information, in adults a transesophageal echo (TEE) is usually necessary. Typically, MRI is performed as well.
Consists of two basic types:
- D-TGA
- L-TGA otherwise known as congenitally-corrected TGA
