What is the difference between the L transposition defect and the D transposition defect?

What is the difference between the L transposition defect and the D transposition defect?

L-transposition of the great arteries (L-TGA) is also known as congenitally corrected transposition of the great arteries. This condition is different from D-transposition of the great arteries (d-TGA). In L-TGA, the right and left lower pumping chambers of the heart (ventricles) are switched.

How rare is 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.

Is transposition of the great arteries heart disease?

Transposition of the great arteries is a serious but rare heart defect present at birth (congenital), in which the two main arteries leaving the heart are reversed (transposed). The condition is also called dextro-transposition of the great arteries.

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. The switch means that the aorta, which normally carries oxygenated blood, carries deoxygenated blood.

Does transposition of the great arteries require surgery?

All infants with transposition of the great arteries need surgery to correct the defect.

What triggers TGA?

Possible triggers of TGA include: Sudden immersion in cold or hot water. Strenuous physical activity. Sexual intercourse.

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 the heart with L transposition?

Like patients with atrial repair of d-TGA, the right ventricle may weaken, leading to congestive heart failure. Abnormally slow heart rhythms may cause fainting or fatigue. The most worrisome slow heart rhythm, complete heart block, is common in l-transposition. Rapid heart rhythms are less common than in d-TGA patients.

When was the transposition of the great vessels first described?

Transposition of the Great Vessels was first described in 1797 by Matthew Baillie. Additional images

Where does deoxygenated blood go in Dextro transposition?

In dextro-Transposition of the great arteries (dextro-TGA) deoxygenated blood from the right heart is pumped immediately through the aorta and circulated to the body and the heart itself, bypassing the lungs altogether, while the left heart pumps oxygenated blood continuously back into the lungs through the pulmonary artery.

What are the four great vessels of the heart?

The four chambers of the heart are the right atrium, the right ventricle, the left atrium, and the left ventricle. The great vessels of the heart include the superior and inferior vena cava, which bring blood from the body to the right atrium, the pulmonary artery, which transports blood from the right ventricle to the lungs.

What are the heart great vessels?

Five great vessels enter and leave the heart: the superior and inferior vena cava, the pulmonary artery, the pulmonary vein, and the aorta. The superior vena cava and inferior vena cava are veins that return deoxygenated blood from circulation in the body and empty it into the right atrium.

What is the great artery?

The great arteries are the primary arteries that carry blood away from the heart, which include: Pulmonary artery: the vessel that carries oxygen-depleted blood from the right ventricle to the lungs.

What is a heart vessel?

The vessels of the heart include the coronary arteries, which supply the heart and the veins and lymph vessels, which drain the heart. These are the blood vessels responsible for taking blood to the all the tissues of the heart with the exception of the fibrous and the parietal serous layers of the pericardium .
