There are two different types of [[Transposition of the great vessels|transposition of the great arteries]], [[Dextro-Transposition of the great arteries|Dextro-transposition of the great arteries]] and [[Levo-Transposition of the great arteries|Levo-transposition of the great arteries]], depending on where the chambers and vessels connect. Dextro-transposition happens in about 1 in 4,000 newborns and is when the right ventricle pumps blood into the aorta and deoxygenated blood enters the bloodstream. The temporary procedure is to create an [[atrial septal defect]]. A permanent fix is more complicated and involves redirecting the pulmonary return to the right atrium and the systemic return to the left atrium, which is known as the [[Senning procedure]]. The [[Rastelli procedure]] can also be done by rerouting the left ventricular outflow, dividing the pulmonary trunk, and placing a conduit in between the right ventricle and pulmonary trunk. Levo-transposition happens in about 1 in 13,000 newborns and is characterized by the left ventricle pumping blood into the lungs and the right ventricle pumping the blood into the aorta. This may not produce problems at the beginning, but will eventually due to the different pressures each ventricle uses to pump blood. Switching the left ventricle to be the systemic ventricle and the right ventricle to pump blood into the pulmonary artery can repair levo-transposition.{{citation needed|date=April 2021}}
