Overview

In complete TGA, the aortic and pulmonary valve appear as double circles, with the aorta anterior and to the right or side by side and to the right of the pulmonary artery.

Echocardiography

Two-dimensional echocardiography identify the spatial relationship between the great arteries and their ventricular origins. In complete TGA, the aortic and pulmonary valve appear as double circles, with the aorta anterior and to the right or side by side and to the right of the pulmonary artery. It is also important to look for right and left branches of the pulmonary artery, and the brachiocaphalic branches of the aortic arch.

Imaging for Dextro-Transposition of the Great Arteries After Atrial Baffle Procedure (DO NOT EDIT)[1][2]

Class I
1. In patients with d-TGA repaired by atrial baffle procedure, comprehensive echocardiographic imaging should be performed in a regional ACHD center to evaluate the anatomy and hemodynamics. (Level of Evidence: B)
2. Additional imaging with TEE, CT, or MRI, as appropriate, should be performed in a regional ACHD center to evaluate the great arteries and veins, as well as ventricular function, in patients with prior atrial baffle repair of d-TGA. (Level of Evidence: B)
Class IIa
1. Echocardiography contrast injection with agitated saline can be useful to evaluate baffle anatomy and shunting in patients with previously repaired d-TGA after atrial baffle. (Level of Evidence: B)
2. TEE can be effective for more detailed baffle evaluation for patients with d-TGA. (Level of Evidence: B)
