Transposition of the great vessels - wikipedia Transposition of the great vessels <Th_colspan="2"> Transposition of the great vessels <Td_colspan="2"> <Td_colspan="2"> Illustration of transposition of the great vessels Specialty Medical genetics Transposition of the great vessels ( TGV ) is a group of congenital heart defects involving an abnormal spatial arrangement of any of the great vessels : superior and / or inferior venae cavae , pulmonary artery , pulmonary veins , and aorta . Congenital heart diseases involving only the primary arteries ( pulmonary artery and aorta ) belong to a sub-group called transposition of the great arteries .

Transposed vessels can present a large variety of atriovenous , ventriculoarterial and / or arteriovenous discordance . The effects may range from a change in blood pressure to an interruption in circulation , depending on the nature and degree of the misplacement and which vessels are involved . Although `` transposed '' literally means `` swapped '' , many types of TGV involve vessels that are in abnormal positions , while not actually being swapped with each other . The terms TGV and TGA are most commonly used in reference to dextro - TGA -- in which the arteries are in swapped positions ; however , both terms are also commonly used , though to a slightly lesser extent , in reference to levo - TGA -- in which both the arteries and the ventricles are swapped ; while other defects in this category are almost never referred to by either of these terms . Dextro - transposition of the great arteries ( edit ) Main article : dextro - Transposition of the great arteries In dextro - Transposition of the great arteries ( dextro - TGA ) deoxygenated blood from the right heart is pumped immediately through the aorta and circulated to the body and the heart itself , bypassing the lungs altogether , while the left heart pumps oxygenated blood continuously back into the lungs through the pulmonary artery . In effect , two separate `` circular '' ( parallel ) circulatory systems are created . It is called a cyanotic congenital heart defect ( CHD ) because the newborn infant turns blue from lack of oxygen . Levo - transposition of the great arteries ( edit ) Main article : Levo - Transposition of the great arteries Levo - Transposition of the great arteries is an acyanotic heart defect in which the primary arteries are transposed , with the aorta anterior and to the left of the pulmonary artery , and the morphological left and right ventricles with their corresponding atrioventricular valves are also transposed . The systemic and the pulmonary circulation are connected . Complications arise from the fact that the right ventricle , which is adapted for pumping blood into the low pressure pulmonary circulation , is being tasked with pumping blood at a much higher pressure against the high resistance of the systemic circulation . Simple and complex TGV ( edit ) In many cases , TGV is accompanied by other heart defects , the most common type being intracardiac shunts such as atrial septal defect including patent foramen ovale , ventricular septal defect , and patent ductus arteriosus . Stenosis , or other defects , of valves and / or vessels may also be present . When no other heart defects are present it is called ' simple ' TGV ; when other defects are present it is called ' complex ' TGV . Risk factors ( edit ) Preexisting diabetes mellitus of a pregnant mother is a risk factor that has been described for the fetus having TGV . X-ray showing characteristic finding in case of Transposition of the great vessels which is called egg on side sign Diagnosis ( edit ) On chest X-ray , transposition of the great vessels typically shows a cardio - mediastinal silhouette appearing as an `` egg on a string '' , wherein in which the enlarged heart represents an egg on its side and the narrowed , atrophic thymus of the superior mediastinum represents the string . Treatment ( edit ) For newborns with transposition , prostaglandins can be given to keep the ductus arteriosus open which allows mixing of the otherwise isolated pulmonary and systemic circuits . Thus oxygenated blood that recirculates back to the lungs can mix with blood that circulates throughout the body . The arterial switch operation is the definitive treatment for dextro - transposition . Rarely the arterial switch is not feasible due to particular coronary artery anatomy and an atrial switch operation is preferred . History ( edit ) TGV was first described in 1797 by Matthew Baillie .
