What happens in transposition of great vessels?

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.

Is TGA treatable?

Transposition of the great arteries (TGA) is a common congenital heart malformation, involving the inversion of both great vessels (aorta and pulmonary artery). It is not compatible with life in the absence of surgical treatment.

Is transposition of the great arteries compatible with life?

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.

What happens to the heart with transposition of the great arteries?

Other heart defects may occur along with transposition of the great arteries. About 25 percent of children with transposition will also have a ventricular septal defect (VSD) .

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.

What happens to a baby with transposition of the heart?

Babies born with transposition are blue. If there are no connections between the right and left side of the heart to allow the oxygen poor and oxygen rich blood to mix, the baby can only survive for a short time (days). Some type of surgical treatment is needed to allow for survival throughout childhood and into adulthood.

What happens to the heart after a mustard transposition?

They may have valve leakage or coronary artery problems, however. People with repaired transposition, especially those who’ve had the Mustard or Senning operation, are at risk of developing heart rhythm abnormalities (arrhythmias). These arrhythmias often arise in the heart’s upper chambers. Your child’s heart rate may be too slow or too fast.
