| corrected transposition of the great vessels | Anatomically or physiologically corrected malposition of the great arteries. In anatomically corrected transposition, they arise from the correct ventricles but have an abnormal relation to each other (actually a malposition rather than a transposition.) In physiologically or functionally corrected transposition, the aorta arises from a systemic ventricle that has the morphologic characteristics of a right ventricle, and the pulmonary artery arises from a "venous" ventricle that has the morphologic characteristics of a left ventricle.

| transposition of great vessels | <embryology> A congenital cardiovascular malformation in which the aorta arises entirely from the right ventricle and the pulmonary artery from the left ventricle, so that the venous return from the peripheral circulation is recirculated by the right ventricle via the aorta to the systemic circulation without being oxygenated in the lungs. There is an intracardiac shunt, increased pulmonary vascularity, cyanosis. The chest X-ray shows that the heart size may be normal at birth, but it gradually enlarges with a globular or egg-on-its-side appearance. (27 Jun 1999) |
|---|---|
| transposition of the great vessels | Congenital malformation in which the aorta arises from the morphologic right ventricle and the pulmonary artery from the morphologic left ventricle resulting in two separate and parallel circulations. The condition is lethal unless some communication exists between the systemic and pulmonic circulation after birth; otherwise, unoxygenated venous blood inappropriately enters the systemic circulation, and oxygenated pulmonary venous blood is inappropriately directed to the pulmonary circulation. The life sustaining communication may be an intra-atrial passage or a patent ductus arteriosus. Synonym: transposition of arterial stems. (05 Mar 2000) |
| vessels of vessels | Nutrient blood vessels which supply the walls of large arteries or veins. (12 Dec 1998) |

| corrected and republished article | The republication of an article to correct, amplify, or restore text and data of the originally published article. (12 Dec 1998) |
| corrected dextrocardia | Displacement and rotation of the heart into the right side of the chest but without mirror transposition of the cardiac chambers. Synonym: dextroversion of the heart, false dextrocardia, type 3 dextrocardia. (05 Mar 2000) |
| bacterial transposition | <molecular biology> A short sequence of DNA (known as a transposon) which can change location on the bacterial genome (the sum total of all of the bacterium's DNA) and contains genes which code for proteins that enable it to change location. They are useful because they can also contain genes for other things, like antibiotic resistance, and because they can be introduced into a bacterial genome by a researcher. (09 Oct 1997) |
| penoscrotal transposition | Deficient ventral penile shaft skin which is buried in scrotum or tethered to scrotal midline by a fold or web of skin. The urethra and erectile bodies are usually normal. Synonym: penis palmatus, penoscrotal transposition. (05 Mar 2000) |
| transposition | <molecular biology> The movement of a piece of DNA around the chromosome (from one gene to another part of the genome), usually through the function of a transposable element. (09 Oct 1997) |
| transposition of arterial stems | Congenital malformation in which the aorta arises from the morphologic right ventricle and the pulmonary artery from the morphologic left ventricle resulting in two separate and parallel circulations. The condition is lethal unless some communication exists between the systemic and pulmonic circulation after birth; otherwise, unoxygenated venous blood inappropriately enters the systemic circulation, and oxygenated pulmonary venous blood is inappropriately directed to the pulmonary circulation. The life sustaining communication may be an intra-atrial passage or a patent ductus arteriosus. Synonym: transposition of arterial stems. (05 Mar 2000) |
| truncus vs. Transposition | <radiology> May look very similar, increased PBF and cyanosis (admixture), distinguishing feature: aortic arch, right aortic arch in 30% of TA vs. Only 5% of TGV (12 Dec 1998) |
| absorbent vessels | The vessels that convey the lymph; they anastomose freely with each other. Synonym: vasa lymphatica, absorbent vessels, lymphatic vessels, lymphatics. (05 Mar 2000) |
| blood vessels | Any of the tubular vessels conveying the blood (arteries, arterioles, capillaries, venules, and veins). (12 Dec 1998) |
| vessels of internal ear | Blood vessels of the internal ear, consisting of the labyrinthine artery and its branches and the labyrinthine veins and their tributaries. Synonym: vasa auris internae. (05 Mar 2000) |
