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 ...
In segmental analysis, this condition is described as atrioventricular discordance (ventricular inversion) with ventriculoarterial discordance. l-TGA is often referred to simply as transposition of the great arteries (TGA); however, TGA is a more general term which may also refer to dextro-transposition of the great arteries (d-TGA).
Anterior view of the heart, with all great vessels labeled. 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 ...
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 ...
In segmental analysis, this condition is described as ventriculoarterial discordance with atrioventricular concordance, or just ventriculoarterial discordance. d-TGA is often referred to simply as transposition of the great arteries (TGA); however, TGA is a more general term which may also refer to levo-transposition of the great arteries (l ...
The Senning procedure is an atrial switch heart operation performed to treat transposition of the great arteries. It is named after its inventor, the Swedish cardiac surgeon Åke Senning (1915–2000), also known for implanting the first permanent cardiac pacemaker in 1958.
Less commonly, babies can have levo-transposition of the great arteries, or l-TGA, with levo meaning that the aorta’s primarily to the “left” of the pulmonary artery. In this form, the great arteries are still connected to the wrong ventricle, but it’s just that the ventricles are the one’s that switch places along with their ...
The great arteries originate from the aortic arches during embryonic development.The aortic arches start as five pairs of symmetrical vessels connecting the heart with the dorsal aorta but then undergo a significant remodelling, [1] in which some of these vessels regress (aortic arches 1 and 2), the 3rd pair of arches contribute to form the common carotids, the right 4th will contribute to the ...
