Transposition of Great Arteries
Parasternal long axis view from a patient with transposition of the great arteries. Note the two great arteries are parallel and the pulmonary artery is positioned posterior to the aorta.

Mustard Procedure
Apical four chamber view in a patient withtransposition of the great arteries after a Mustard repair. Note the intra-atrial baffle (arrow) directing the pulmonary venous flow into the right side atrium. The right atrium and right ventricle are dilated.
