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.
