What is the transposition of the great arteries?

What should you know about it?

Transposition of the great arteries is a rare birth defect where the two main arteries leaving the heart are swapped and connected to the wrong heart chambers.

THE TWO SWITCHED ARTERIES ARE

The pulmonary artery normally takes blood from the heart to the lungs. The aorta usually carries blood from the heart to the rest of the body.

Your arteries are part of the system that moves blood throughout your body. Most arteries carry blood that’s full of oxygen, but the pulmonary arteries are different—they carry blood that’s low in oxygen to the lungs.

What is the transposition of the great arteries?

The type of a condition where the heart’s main arteries are swapped.

Transposition of the great arteries

This type, known as dextro-transposition of the great arteries (d-TGA), limits the amount of oxygen-filled blood that flows to the body. It’s usually found during pregnancy or shortly after birth. Without treatment, it can lead to serious health problems or even be life-threatening.

Symptoms

signs

What signs or problems can show up with transposition of the great arteries?

Indications of transposition of the great arteries can include:

Blue skin or lips (Cyanosis)

Due to low oxygen in the blood, babies may have a bluish tint to their skin, lips, or fingernails.

Shortness of breath

The baby may breathe rapidly or seem to struggle to breathe because the body isn’t getting enough oxygen.

Poor feeding

Babies with TGA might get tired quickly during feeding and may not gain weight as they should.

treatments

What treatments are usually suggested for transposition of the great arteries?

The treatment options usually depend on the specific type of TGA a person has. The common treatment options include:

Arterial switch procedure

This surgery changes the positions of your baby’s aorta and pulmonary artery, allowing blood to flow properly through the heart and to the rest of the body. Before suggesting a major surgery, the doctors usually delay with other treatment options that include

Prostaglandin

This medicine helps keep a blood vessel called the ductus arteriosus from closing. Before birth, babies use this vessel for blood flow, but it normally closes soon after. Keeping it open allows more oxygen-rich blood to flow to your baby’s body.

Septostomy procedure

A balloon atrial septostomy is a basic procedure where a thin tube is used to widen the opening between the upper parts of the heart. This helps the blood mix more, allowing more oxygen to reach your baby’s body.
