What is congenitally corrected TGA?

In congenitally corrected transposition of the great arteries (CCTGA), the heart twists abnormally during fetal development, and the ventricles are reversed: The stronger left ventricle pumps blood to the lungs and the weaker right ventricle has the harder chore of pumping blood to the entire body.

What does congenitally corrected mean?

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.

What is TGA in congenital heart disease?

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.

When a newborn has a transposition of the great arteries TGA The only chance for survival is?

Untreated, over 50 percent of infants with transposition will die in the first month of life. Ninety percent will die in the first year.

How long do people with TGA live?

Corrected transposition of the great arteries is a rare condition, and few patients with this abnormality survive past 50 years of age because of associated congenital defects or the subsequent development of atrioventricular valvular insufficiency or heart block or both.

What causes corrected transposition of the great arteries?

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 causes baby TGA?

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.

What is the survival rate of transposition of the great arteries?

Actuarial analysis of the data indicates that with this plan of management, approximately 50 percent of newborns with transposition of the great arteries will survive 5 years with excellent function and an additional 15 to 20 percent will survive with one or more medical handicaps.

How long do babies with TGA live?

According to the National Heart, Lung, and Blood Institute (NHLBI), TGA affects roughly 5 out of every 10,000 babies. The defect is found more frequently in Caucasians. Untreated, more than 50% of infants with transposition will die in the first month of life, 90 % in the first year.

What is TGA and VSD?

Normally, these connections would close shortly after birth. Common heart defects that can happen with TGA include an opening in the ventricular septum, called a ventricular septal defect (VSD). This is a hole between the 2 lower chambers of the heart. This allows oxygen-poor and oxygen-rich blood to mix.

What is the difference between simple and complex D-TGA?

Simple and complex d-TGA Stenosis of valves or vessels may also be present. When no other heart defects are present it is called ‘simple’ d-TGA; when other defects are present it is called ‘complex’ d-TGA.

Is TGA genetic?

What causes TGA? There is no known cause of TGA. Some patients with TGA have genetic disorders. TGA does not run in families, but there is an increased chance of having a congenital heart defect if a relative also was born with a heart defect.

Can TGA be cured?

All children with a TGA will need to have surgery to fix it. Most children who have surgery for this condition will grow and develop normally. Your child will still need to see his or her heart doctor for checkups and may require more surgery in the future.

What are the types of TGA?

There are three types of thermogravimetric analyzers: suspension system, top-loading system and horizontal system.

Can you live a long life with congenital heart disease?

As medical care and treatment have improved, babies and children with congenital heart defects (CHDs) are living longer and healthier lives. Most are now living into adulthood. Ongoing, appropriate medical care can help children and adults with a CHD live as healthy as possible.
