What is the difference between TGA and CCTGA?
Congenitally corrected transposition of the great arteries (CCTGA) is a rare heart defect in which the heart’s lower half is reversed. It is also called L-TGA. It is different from and much less common than “regular” transposition of the great arteries (TGA or D-TGA).
What is D-TGA and L-TGA?
The two common forms of transposition include D-TGA, which presents with cyanosis early in life, and L-TGA, which on the other hand, may permit survival to adulthood without being diagnosed in childhood.
Why is it called D transposition?
Dextro-Transposition 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.” Because a baby with this defect may need surgery or other procedures soon after birth.
Is TGA and TGV the same?
The terms TGV and TGA are most commonly used in reference to dextro-TGA – in which the two main 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 …
What causes TGA of heart?
Several things may increase the risk of a baby being born with transposition of the great arteries, including: A history of German measles (rubella) or another viral illness in the mother during pregnancy. Drinking alcohol or taking certain medications during pregnancy. Smoking during pregnancy.
Why is it called congenitally corrected TGA?
Although the two heart valves and the two great arteries (the pulmonary artery (5) and the aorta (6) are transposed or exit from the “wrong” ventricle, the blood flows to the correct place because the ventricles are also reversed. That is why this heart defect is called “corrected” transposition.
What causes d-TGA?
Transposition of the great arteries occurs during pregnancy when the baby’s heart is developing. The cause is most often unknown. To understand transposition of the great arteries, it may be helpful to know how the heart typically pumps blood.
What are the types of TGA?
There are three types of thermogravimetric analyzers: suspension system, top-loading system and horizontal system.
What is a TGA baby?
Transposition of the great arteries (TGA) is a type of heart defect that your baby is born with (congenital). In this condition, the two arteries that carry blood from the heart to the lungs and body aren’t connected as they should be. They are reversed (transposed).
What is TGA surgery?
Arterial switch is a surgical procedure and the main treatment to correct transposition of the great arteries (TGA). Almost all children with TGA undergo the arterial switch repair (also called the Jatene repair). Soon after birth, babies with TGA become very sick because of a severe lack of oxygen.
What is PA band surgery?
Pulmonary artery banding (PAB) is a palliative surgical technique used for the correction of congenital cardiac defects, characterized by pulmonary over-circulation caused by left-to-right shunting of blood. PAB is reserved for palliation in a certain subset of infants with complex congenital heart disease.
Does TGA have murmur?
Transposition of the great arteries with ventricular septal defect and left ventricular outflow tract obstruction: Cyanosis is prominent at birth, and the findings are similar to those of infants with tetralogy of Fallot. A single second heart sound (S2) and a systolic ejection murmur may be present.
