What is transposition of the heart?
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.
What is an inverted heart?
Ventricular inversion refers to a specific congenital heart defect in which the ventricles are exchanged in position so that the left atrium enters the right ventricle and the right atrium enters the left ventricle.
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.
How is TGA treated?
How is TGA treated in a child?
- Supplemental oxygen or a ventilator (a machine that helps do the work of breathing for the baby)
- Different types of medicine given by IV. This will help your baby’s heart and lungs work better.
- A medicine called prostaglandin E1. This is used to keep the ductus arteriosus open.
What does Levocardia mean?
Strictly speaking, levocardia means that the cardiac apex is left sided. Isolated levocardias are those hearts that are left sided when situs inversus is present.
What is an I transposition heart?
A heart in which the lower section is fully reversed. This malformation of the heart causes a reversal in the normal blood flow pattern because the right and left lower chambers of the heart are reversed. The I-transposition, however, is less dangerous than a d-transposition because the great arteries are also reversed.
What is transposition of the great arteries?
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).
What does the pulmonary artery do in transposition?
It carries oxygen-rich blood out of your heart back to the rest of your body. 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.
How is transposition of the heart treated in babies?
The most common type of surgery to correct transposition when identified in babies is the arterial switch operation. During this operation, the surgeon moves the great arteries so they are connected to the correct pumping chamber.
