There are a lot of neonatal conditions covered, seen in high level NICU/NCCU Units.

A/N: There is a fantastic podcast that goes into detail re: TGA.

They are doctors talking about it, but it went into a lot of symptoms and presentations of TGA. Worth a listen if you have time.
Alternatively, here is a couple videos instead:
(I recommend the second one)
Transposition of the Great Arteries (TGA)
What are the Great Arteries? The pulmonary artery and the aorta are the arteries in question in TGA. In normal physiology, the pulmonary artery attaches to the right ventricle, and delivers deoxygenated blood to the lungs, and the aorta transports oxygenated blood from the left ventricle to the body.

In TGA however, these vessels are 'transposed' (essentially, swapped), so that the aorta is connected to the R) ventricle, and the pulmonary artery is connected to the L) ventricle.
In Dextra TGA (the most common form), this means that instead of normal circulation, we end up with something called 'parallel circulation,' where we have deoxygenated blood travelling from the R) ventricle to the body, into the R) atrium, to the R) ventricle, and back to the body without being oxygenated, and conversely, we have oxygen rich blood arriving at the heart through the L) atrium, flowing into the L) ventricle, and then back to the lungs and into the L) atrium without actually reaching the body.
