Beside this, is transposition of the great arteries hereditary?

In most cases of TGA, only one family member is affected. The findings of some studies have suggested that TGA is a sporadic defect, while other studies have found that the risk for TGA to occur in a sibling of an affected individual is in the range of 0.2% - 1.4%.

Likewise, how do you fix the transposition of the great arteries? 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).

Furthermore, how rare is transposition of the great arteries?

Transposition of the great arteries (TGA), also referred to as complete transposition, is a congenital cardiac malformation characterised by atrioventricular concordance and ventriculoarterial (VA) discordance. The incidence is estimated at 1 in 3,500–5,000 live births, with a male-to-female ratio 1.5 to 3.2:1.

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, 90 percent in the first year. When a newborn with significant cyanosis is first seen, they are often placed in supplemental oxygen.

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. Throughout history, physicians classified TGA as a condition that causes blue babies and hypothesized it was a fatal condition.

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.

How many babies are born with transposition of the great arteries?

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.

What is the cause of transposition of the great vessels?

Because of this, transposition of the great arteries is called a cyanotic congenital heart defect. Although some factors, such as genetics, rubella or other viral illnesses during pregnancy, maternal age over 40, or maternal diabetes, may increase the risk of this condition, in most cases the cause is unknown.

What causes baby TGA?


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).

Is Tetralogy of Fallot a disability?

You can get disability benefits if you have congenital heart disease that causes cyanosis or severe functional limitations on your ability to work. If your type of congenital heart disease is so severe that you are unable to work, you may be able to get disability benefits from Social Security (SSDI or SSI).

Is Hole in Heart hereditary?

The condition can be genetic (hereditary). Some congenital heart defects are the result of alcohol or drug use during pregnancy. A hole between 2 chambers of the heart is an example of a very common type of congenital heart defect.

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.

Can the left ventricle be repaired?

Left ventricular reconstructive surgery is a procedure sometimes used to treat heart failure. Left ventricular reconstructive surgery (or aneurysm repair surgery) allows the surgeon to remove the scarred, dead area of heart tissue and/or the aneurysm and return the left ventricle to a more normal shape.

Are arteries oxygen rich or poor?


Arteries carry oxygen-rich blood away from your heart, and veins carry oxygen-poor blood back to your heart. In pulmonary circulation, though, the roles are switched. It is the pulmonary artery that brings oxygen-poor blood into your lungs and the pulmonary vein that brings oxygen-rich blood back to your heart.

How do you enlarge your arteries?

A heart-healthy diet contains plenty of good fats and low amounts of bad fats.
  1. Add more good fats to your diet. Good fats are also called unsaturated fats.
  2. Cut sources of saturated fat, such as fatty meat and dairy.
  3. Eliminate artificial sources of trans fats.
  4. Increase your fiber intake.
  5. Cut back on sugar.

What causes heart problems in newborns?

A congenital heart defect (CHD) is a heart problem that a baby has at birth. It is caused by abnormal formation of the heart during growth in the womb. In most cases, when a baby is born with a congenital heart defect, there is no known reason for it.

What is corrected transposition of the great arteries?

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. A normal heart is divided into two sides. The right side pumps blood from the body into the lungs.

Which condition is consistent with the cardiac defect of transposition of the great vessels?


Transposition of the great arteries is the most common cyanotic (low blood oxygen) congenital heart condition.

How is TGA diagnosed?

Diagnosis of TGA may require some or all of these tests:
  1. Echocardiogram (also called "echo" or ultrasound): sound waves create an image of the heart.
  2. Electrocardiogram (ECG): a record of the electrical activity of the heart.
  3. Chest X-ray.
  4. Pulse oximetry: a noninvasive way to monitor the oxygen content of the blood.

What does TGA stand for in medical terms?

Neurology. Transient global amnesia (TGA) is a neurological disorder whose key defining characteristic is a temporary but almost total disruption of short-term memory with a range of problems accessing older memories.
