How is transposition of the great arteries diagnosed?


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.

What happens TGA?

In TGA, your child’s aorta is connected to the right ventricle, and the pulmonary artery is connected to the left ventricle. This is the reverse of a normal heart. A newborn with TGA will usually have bluish skin color in the first days of life. All children with a TGA will need to have surgery to fix it.

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.

Transient global amnesia (TGA) occurs in approximately 3 to 10 people out of every 100,000.

What is the life expectancy for a child with congenital heart defect?

Survival. About 97% of babies born with a non-critical CHD are expected to survive to one year of age. About 95% of babies born with a non-critical CHD are expected to survive to 18 years of age.

Is TGA heart disease?

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).

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 much does arterial switch surgery cost?

The median costs were $60,000, in 2012 dollars (range: $25,000 to $549,000). The median age at operation was 5 days (range: 1 to 12 days).

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

If there are no unusual risk factors, more than 98 percent of surgically-treated infants survive their infancy. Most children who’ve had TGA surgery recover and grow normally, although they can be at some risk in the future for arrhythmias, leaky valves and other heart issues.

Can transient global amnesia be caused by stress?

What causes transient global amnesia is not fully known. But, in some cases, migraines, an intense workout, sex, or stress may cause an episode.
