Transposition of the Great Arteries Procedure Flashcards
(10 cards)
What is TGA?
Transposition of the great arteries
A congenital heart defect where the aorta and pulmonary artery are switched.
What signs may indicate worsening cyanosis in an infant with TGA?
Cyanosis and respiratory distress
These signs occur if the ductus arteriosus closes or if the foramen ovale becomes restrictive.
What drug may be used to reduce cyanosis in infants with TGA?
Prostaglandin E1
This drug helps reopen the ductus arteriosus.
What is a Balloon Septostomy?
A procedure to create a larger opening in the atrial septum
It involves using a catheter with an uninflated balloon to tear the septum.
How is the Balloon Septostomy performed?
A catheter is inserted from a leg vein into the heart and through the foramen ovale, where the balloon is inflated and withdrawn
This creates a larger opening for better mixing of blood.
What is the purpose of the Balloon Septostomy?
To temporarily stabilize the neonate
It is not a permanent solution.
What surgical procedure is performed about one week after birth for infants with TGA?
Arterial Switch Operation
This procedure corrects the defect by re-routing blood flow to mimic a normal heart.
What does the Arterial Switch Operation involve?
Connecting the aorta to the left ventricle and the pulmonary artery to the right ventricle
It ensures proper blood flow in the heart.
What happens to the coronary arteries during the Arterial Switch Operation?
They are reconnected to the aorta
This allows the heart muscle to receive oxygenated blood.
What additional procedures are done during the Arterial Switch Operation?
Closure of the foramen ovale and patent ductus arteriosus (PDA)
These closures are part of the surgical repair.
