How long can you live with transposition of the great arteries?

How long can you live with transposition of the great arteries?

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. We describe four men with uncomplicated C-TGA.

Is transposition of the great vessels 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.

Does transposition of the great arteries require surgery?

All infants with transposition of the great arteries need surgery to correct the defect.

How successful is TGA surgery?

Although the arterial switch is a major surgical procedure, the results are excellent. Ninety-nine percent of the surgeries are successful. This operation will require the use of cardiopulmonary bypass (heart-lung machine).

Can transposition of the great arteries cause brain damage?

Brain injury, impaired brain growth, and long-term neurodevelopmental problems are common in children with transposition of the great arteries.

What happens in transposition of great arteries?

In transposition of the great arteries, the positions of the pulmonary artery and the aorta are switched. The pulmonary artery is connected to the left ventricle, and the aorta is connected to the right ventricle.

Why does transposition of great arteries occur?

Transposition of the great arteries occurs during fetal growth when your baby’s heart is developing. Why this defect occurs is unknown in most cases. Normally, the pulmonary artery — which carries blood from your heart to your lungs to receive oxygen — is attached to the lower right chamber (right ventricle).

How long does TGA surgery take?

The surgery to repair TGA is known as an arterial switch operation. A pediatric heart surgeon performs the surgery. The surgery lasts about 4 to 6 hours. It takes place in an operating room in a hospital.

Is TGA common?

Occurrence. The Centers for Disease Control and Prevention (CDC) estimates that about 1,153 babies are born with TGA each year in the United States. This means that every 1 in 3,413 babies born in the US is affected by this defect.

Is TGA hereditary?

Background: Transposition of the great arteries (TGA) is considered to be associated only rarely with genetic syndromes and to have a low risk of precurrence among relatives of affected patients.

How is TGA treated?

How is TGA treated?

1. Supplemental oxygen or a ventilator. This is a machine that helps do the work of breathing for the baby.
2. Different types pf medicine given by IV. This will help your baby’s heart and lungs work better.
3. A medicine called prostaglandin E1. This is used to keep the ductus arteriosus open.

How rare is TGA?

What causes TGA?

The exact cause of transient global amnesia (TGA) is unknown. However, some research suggests that TGA results from lack of sufficient blood flow (a condition called ischemia) or oxygen flow (a condition called hypoxia) to the brain. In some cases, TGA may be related to seizure activity in the brain.

What triggers TGA?

Possible triggers of TGA include: Sudden immersion in cold or hot water. Strenuous physical activity. Sexual intercourse.

Does TGA lead to dementia?

Age and diabetes were significantly associated with dementia in TGA. Conclusions: TGA increased the long-term risk of dementia. Age and diabetes were notable factors associated with dementia after TGA.

Is TGA a stroke?

Transient global amnesia is a sudden, temporary episode of memory loss that can’t be attributed to a more common neurological condition, such as epilepsy or stroke. During an episode of transient global amnesia, your recall of recent events simply vanishes, so you can’t remember where you are or how you got there.

Why is transposition of the great arteries fatal?

Is TGA life threatening?

Typically diagnosed within the first hours after birth, TGA is life threatening, and in order to survive babies need special therapy urgently.

How can transposition of the great arteries be corrected?

Surgery

1. 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.
2. Atrial switch operation. In this surgery, the surgeon makes a tunnel (baffle) between the heart’s two upper chambers (atria).

How is transposition of great arteries diagnosed?

Echocardiogram. An echocardiogram is an ultrasound of the heart — it uses sound waves that bounce off your baby’s heart and produce moving images that can be viewed on a video screen. Doctors use this test to diagnose transposition of the great arteries by looking at the position of the aorta and the pulmonary artery.

What does transposition of the great arteries mean?

Transposition of the great arteries (TGA) is a type of congental heart defect. This means that your baby is born with it. In this condition, the large blood vessels that carry blood from the heart to the lungs and body aren’t connected as they should be.

Are there prenatal tests for transposition of the great arteries?

Prenatal tests for transposition of the great arteries aren’t usually done unless your doctor suspects your baby may have congenital heart disease.

How often does transposition of the great vessels occur?

Surgery is an essential part of the treatment plan in most cases. Also known as transposition of the great vessels (TGV), TGA is a rare but serious disorder that affects one of every 4,000 to 10,000 births. 1  There are two types of TGA that differ based on the vessels and heart chambers involved: 1 

How are the great arteries of the heart reversed?

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.

What are the causes of transposition of the great arteries?

Although the exact cause of transposition of the great arteries is unknown, several factors may increase the risk of a baby being born with this condition, including: A history of German measles (rubella) or another viral illness in the mother during pregnancy Drinking alcohol during pregnancy Smoking during pregnancy A mother who has poorly controlled diabetes

What does transposition of great vessels mean?

Transposition of the great vessels. Transposition of the great vessels ( TGV ) is a group of congenital heart defects involving an abnormal spatial arrangement of any of the great vessels: superior and/or inferior venae cavae, pulmonary artery, pulmonary veins, and aorta.

What are the four great vessels of the heart?

The four chambers of the heart are the right atrium, the right ventricle, the left atrium, and the left ventricle. The great vessels of the heart include the superior and inferior vena cava, which bring blood from the body to the right atrium, the pulmonary artery, which transports blood from the right ventricle to the lungs.

What is the great artery?

The great arteries are the primary arteries that carry blood away from the heart, which include: Pulmonary artery: the vessel that carries oxygen-depleted blood from the right ventricle to the lungs.
