Levo-Transposition of the great arteries (also known as Levo-TGA, congenitally corrected TGA, double discordance, or ventricular inversion) is a rare, 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 ...
Great vessels are the large vessels that bring blood to and from the heart. [1] These are: [1] [2] [3] Superior vena cava; Inferior vena cava; Pulmonary arteries; Pulmonary veins; Aorta; Transposition of the great vessels is a group of congenital heart defects involving an abnormal spatial arrangement of any of the great vessels.

transposition of the great vessels; Ventricular and atrial septal defects. Deranged abdominal organ asymmetry: [citation needed] The stomach and spleen are prone to isolated reversal; The stomach, liver, and a single adrenal gland are occasionally found in the midline. Organ malformations: [citation needed] asplenia and polysplenia often lead ...
The procedure was developed to treat transposition of the great vessels, eponymously known as blue baby syndrome. This is a condition in which the aorta and pulmonary artery are attached to the heart in an opposite order from what is usually present at birth, resulting in the aorta being the outflow tract for the right ventricle and the ...
Transposition of teeth; Penoscrotal transposition; Transposition (horizontal gene transfer), the transfer of genetic material between organisms other than by vertical gene transfer; Transposons, or genetic transposition, a mutation in which a chromosomal segment is transferred to a new position on the same or another chromosome
In anatomy, the venae cavae (/ ˈ v iː n i ˈ k eɪ v i /; [1] sg.: vena cava / ˈ v iː n ə ˈ k eɪ v ə /; from Latin 'hollow veins') [2] are two large veins (great vessels) that return deoxygenated blood from the body into the heart. In humans they are the superior vena cava and the inferior vena cava, and both empty into the right atrium ...
In dextro-transposition of the great arteries, at the initial arterial switch a Jatene procedure is normally done in conjunction to switch the coronary arteries as well, as they originate from the aorta. The Jatene procedure is ideally performed during the second week of life, before the left ventricle adjusts to the lower pulmonary pressure.
there is an opening or passage between the atria, ventricles, and/or great vessels; and, right heart pressure is higher than left heart pressure and/or the shunt has a one-way valvular opening. Small physiological, or "normal", shunts are seen due to the return of bronchial artery blood and coronary blood through the Thebesian veins , which are ...
