EDUCATIONAL SERIES IN CONGENITAL HEART DISEASE: Echocardiographic assessment of transposition of the great arteries and congenitally corrected transposition of the great arteries.

Echocardiographic assessment of patients with transposition of the great arteries and congenitally corrected transposition requires awareness of the morphology and commonly associated lesions. The pre-operative echocardiography should include a full segmental and sequential analysis. Post-operative assessment is not possible without awareness of the type of surgical procedure performed and consists of assessing surgical connections and residual lesions.
