TGA case 1

123
Clip showing first the normal 4 chamber view, with a wide open foramen ovale.
Pulmonary artery arises from the left ventricle.
The lateral branching, typical for the pulmonary artery, is clearly visible.
The aorta arises from the right artery, into the ‘two vessel view’ (instead of three vessel view).
This comprises the aortic arch in transverse section and the superior vena cava.
Clip of the 3VV, showing only 2 vessels: the aorta and superior vena cava.
This is typical for TGA, although not present in all cases.
The spatial relationship of the aorta and pulmonary artery determines how this plane looks like.
Clip showing ‘lateral branching’, typical for the pulmonary artery.
The pulmonary artery arises from the left ventricle.
