What is the transposition of the 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.

What is Levo transposition of the great arteries?

Levo- or L-looped transposition of the great arteries (L-TGA) is a rare form of congenital heart disease characterized by atrioventricular (AV) and ventriculoarterial discordance (figure 1). It is also commonly referred to as congenitally corrected TGA, double discordance, or ventricular inversion.

What are Malposed great arteries?

[1] had defined this as any situation in which aorta arises from left ventricle but to the left of the pulmonary artery. Basically, this occurs with ventriculoarterial concordance in which the great vessels arise parallel instead of a twisting fashion.

What are the great arteries?

The “great arteries” are the pulmonary artery and the aorta. Normally, the pulmonary artery is connected to the heart’s lower-right chamber (the right ventricle). The right ventricle pumps oxygen-poor blood into the pulmonary artery, which carries that blood into the lungs.

Can you live with TGA?

This is the opposite of a normal heart. Babies can’t live with this condition unless they get treatment. TGA may occur on its own.

How long can you 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.

What is the difference between D TGA and L-TGA?

The two common forms of transposition include D-TGA, which presents with cyanosis early in life, and L-TGA, which on the other hand, may permit survival to adulthood without being diagnosed in childhood.

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.

Is TGA 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.

How rare is Cctga?

Congenitally corrected transposition of the great arteries (CCTGA) is a rare heart defect. Only 0.5 to 1 percent of all people with heart defects have CCTGA. This means there are about 5,000 to 10,000 people in the United States with this condition.

How long do TGA patients live?

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.

Why are there complications with the transposition of the great vessels?

Complications arise from the fact that the right ventricle, which is adapted for pumping blood into the low-pressure pulmonary circulation, is being tasked with pumping blood at a much higher pressure against the high resistance of the systemic circulation .

What are the diseases of the great vessels?

Less common cardiac and great vessel diseases such as congenital heart disease, neoplasms, and diseases of the pericardium are described in less detail. The last topic, monitoring devices and postoperative changes, is one with which students should be familiar.

How are the great vessels of the heart transposed?

Subcostal echocardiographic view showing discordant ventriculoarterial connections together with the presence of parallel, rather than crossing, great arteries arising from the ventricles. Transposed vessels can present a large variety of atriovenous, ventriculoarterial and/or arteriovenous discordance.

What do you call transposition of the great arteries?

Levo-transposition of the great arteries. In this rare type of transposition of the great arteries — called levo-transposition of the great arteries or sometimes referred to as congenitally corrected transposition — the two ventricles are switched so that the left ventricle is on the heart’s right side and receives blood from the right atrium,…
