Video 31.13 Left aortic arch with normal branching. Echocardiogram in a transverse orientation from a suprasternal notch window
Left aortic arch with normal branching. Echocardiogram in a transverse orientation from a suprasternal notch window demonstrating the transverse aortic arch coursing to the left of the echo-bright trachea. The first branch off the arch is the right innominate artery, which is then seen to bifurcate into the right common carotid and right subclavian arteries. The second and third branches off the arch are the left common carotid and right subclavian arteries, respectively.
