Is transposition of the great arteries hereditary?

Is transposition of the great arteries 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 long can someone 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.

Can a child have transposition of the great arteries?

Other heart defects may occur along with transposition of the great arteries. About 40-45% of children with TGA will also have a ventricular septal defect (VSD). Early detection of TGA is vital. How can it be spotted? Mostly TGA is diagnosed during the 20 week pregnancy scan . But it can be missed.

Can a heart defect be caused by transposition of the great arteries?

Unless there is some place in the circulation where the oxygen-rich and oxygen-poor blood can mix, all of the organs of the body will be deprived of necessary oxygen. Other heart defects may occur along with transposition of the great arteries. About 40-45% of children with TGA will also have a ventricular septal defect (VSD).

Where does the blood go after transposition of the great arteries?

Oxygen-poor blood circulates through the right side of the heart and back to the body without passing through the lungs. Oxygen-rich blood circulates through the left side of the heart and directly back into the lungs without being circulated to the rest of the body.

When do you know if your baby has transposition?

But it can be missed. Often, a fetal echocardiogram is required to make a diagnosis of transposition in a fetus. If not spotted during pregnancy or on delivery, a baby will begin to display signs of heart failure in the hours and days after birth.

What does transposition of the great arteries mean?

Transposition of the great arteries (TGA) is a complex congenital heart defect. In a normal heart, there are two large arteries that carry blood out of the heart.

What happens to babies with dextro Transposition of the Great?

Infants who have these surgeries are not cured; they may have lifelong complications. A child or adult with d-TGA will need regular follow-up visits with a cardiologist (a heart doctor) to monitor their progress and avoid complications or other health problems. With proper treatment, most babies with d-TGA grow up to lead healthy, productive lives.

What happens to a baby with corrected transposition?

Physical findings: Most babies with corrected transposition are born at term and are a normal weight and length. Again, if the only problem is the reversal in position of the ventricles, the examination will be normal. If a VSD, pulmonary stenosis, and/or a leaky tricuspid valve is present, a heart murmur is heard.

Why are the pulmonary and aorta arteries transposed?

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.
