What is transposition of the great arteries?
Español (Spanish) Dextro-Transposition (pronounced DECKS-tro trans-poh-ZI-shun) of the Great Arteries or d-TGA is a birth defect of the heart in which the two main arteries carrying blood out of the heart – the main pulmonary artery and the aorta – are switched in position, or “transposed.”
How do you fix the transposition of the great arteries?
Surgery
- Arterial switch operation. This is the most common surgery used to correct transposition of the great arteries. Surgeons usually perform this surgery within the first month of life.
- Atrial switch operation. In this surgery, the surgeon makes a tunnel (baffle) between the heart’s two upper chambers (atria).
Why is transposition of the great arteries fatal?
Potential complications of transposition of the great arteries include: Lack of oxygen to tissues. Your baby’s tissues will receive too little oxygen (hypoxia). Unless there’s some mixing of oxygen-rich blood and oxygen-poor blood within your baby’s body, he or she won’t be able to survive.
Is transposition of the great arteries fatal?
Transposition of the great arteries or TGA is a potentially fatal congenital heart malformation where the pulmonary artery and the aorta are switched. The switch means that the aorta, which normally carries oxygenated blood, carries deoxygenated blood.
What is the difference between D TGA and L-TGA?
L-transposition of the great arteries (L-TGA) is also known as congenitally corrected transposition of the great arteries. This condition is different from D-transposition of the great arteries (d-TGA). In L-TGA, the right and left lower pumping chambers of the heart (ventricles) are switched.
What is Levo transposition?
Levo- or L-looped transposition of the great arteries (L-TGA) is a rare form of congenital heart disease characterized by atrioventricular (AV) and ventriculoarterial discordance (figure 1). It is also commonly referred to as congenitally corrected TGA, double discordance, or ventricular inversion.
What are Malposed great arteries?
[1] had defined this as any situation in which aorta arises from left ventricle but to the left of the pulmonary artery. Basically, this occurs with ventriculoarterial concordance in which the great vessels arise parallel instead of a twisting fashion.
What is transposition with example?
For example, 5x + 10 = 15 is an algebraic equation where 15 represents the right-hand side (RHS) and 5x + 10 represents the left-hand side (LHS) of the equation. The process of isolating quantities across the equal sign of an equation is called transposition.
What is transportation of the great arteries?
Transposition of the great arteries (TGA) is a heart defect that occurs from birth ( congenital ). The two major arteries that carry blood away from the heart — the aorta and the pulmonary artery — are switched (transposed). The cause of TGA is unknown. It is not associated with any one common genetic abnormality.
What does transposition of great vessels mean?
transposition of great vessels a congenital heart defect in which the position of the chief blood vessels of the heart is reversed, so that the aorta arises from the right ventricle instead of the left and the pulmonary artery emerges from the left ventricle rather than from the right.
What are the major arteries of the body?
Arteries and your circulatory system. The systemic circuit.
What is the great artery?
In transposition of the great arteries (TGA), the “great” arteries, the aorta and the right ventricle, are reversed in their origins from the heart. The aorta is connected to the right ventricle and the pulmonary artery is connected to the left ventricle — exactly the opposite of a normal heart’s anatomy.
