How long does arterial switch procedure take?

How long does arterial switch procedure take?

The surgery to repair TGA is known as an arterial switch operation. A pediatric heart surgeon performs the surgery. The surgery lasts about 4 to 6 hours. It takes place in an operating room in a hospital.

Does transposition of the great arteries require surgery?

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

How is transposition of the great arteries treated?

Surgery: Within a baby’s first two weeks, transposition of the great arteries is surgically repaired through a procedure called an “arterial switch.” While supported by a heart-lung machine, the aorta and pulmonary arteries are disconnected, then “switched” and reconnected to their proper ventricles.

What is a TGA operation?

In transposition of the great arteries (TGA), the “great” arteries, the aorta and the right ventricle, are reversed in their origins from the heart. The aorta is connected to the right ventricle and the pulmonary artery is connected to the left ventricle — exactly the opposite of a normal heart’s anatomy.

How successful is TGA surgery?

The survival of children with transposition has improved dramatically over recent decades. When there are no unusual risk factors identified, over 95 percent of infants successfully undergo surgery in the newborn period.

Is TGA common?

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.

Why 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.

Is TGA serious?

Transient global amnesia (TGA) is a rare medical condition in which a person experiences a sudden episode of memory loss. During a TGA episode, a person cannot form new memories (a condition called anterograde amnesia) and has difficulty recalling recent memories (a condition called retrograde amnesia).

What triggers TGA?

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

When to have transposition of the great arteries surgery?

All children with transposition of the great arteries will require open heart surgery to treat the defect. Without surgical repair, the overwhelming majority of patients with TGA will not survive their first year. The surgery, known as the arterial switch operation, is typically performed within a few days of birth.

How is an arterial switch surgery carried out?

The balloon is then inflated and the catheter is pulled back to the right atrium. Early surgery is essential and involves the ” Arterial Switch Operation”, which is carried out in the first week or two of life and corrects the abnormality.

Who is the founder of the arterial switch?

The Jatene procedure, arterial switch operation or arterial switch, is an open heart surgical procedure used to correct dextro-transposition of the great arteries (d-TGA); its development was pioneered by Canadian cardiac surgeon William Mustard and it was named for Brazilian cardiac surgeon Adib Jatene, who was the first to use it successfully.

What are the procedures for transposition of the Great?

Atrial Switch Operation In the past, most patients with TGA underwent either a palliative procedure or an atrial switch operation. The atrial baffle procedures (Mustard and Senning operations) reroute the systemic venous return to the LV and the pulmonary venous return to the RV, thus allowing for physiologic correction in transposition.
