dextro-Transportation of the Great Arteries (d-TGA) Flashcards
What does d-TGA stand for?
dextro-Transportation of the Great Arteries
What is special for infants with d-TGA?
Their MPA and Aorta are switched
What happens if you have d-TGA?
Deoxygenated blood that comes back to the heart (through the vena cava) is pumped back to the body. And oxygenated blood that comes back from the lungs (through the pulmonary veins) goes back to the lungs.
What do infants with d-TGA often also have? (2) What is the purpose of these?
Infants with d-TGA often also have other CHDs (such as ASD or VSD) and patent ductus arteriosus. These other CHDs and patent ductus arteriosus mix deoxygenated and oxygenated blood so that some oxygenated blood gets pumped to the body and some deoxygenated blood gets pumped to the lungs.
What is a patent ductus arteriosus (PDA)?
Patent ductus arteriosus: An extra blood vessel that connects the top of the MPA and the bottom of the arcus aortae.
When can symptoms of d-TGA occur?
Symptoms of d-TGA can occur at birth or very soon afterwards.
What do the severity of the symptoms of d-TGA depend on? (1)
The severity of the symptoms of d-TGA depend on how much oxygenated blood can be pumped throughout the body.
What are some symptoms of d-TGA? (2)
Some symptoms of d-TGA include cyanosis and a pounding heart.
What is required for all babies born with d-TGA?
Surgery is required for all babies born with d-TGA
What does surgery do to help treat d-TGA?
Surgery helps maintain, enlarge, and create openings that’ll deliver oxygenated blood to the body
How many types of surgeries are there to repair d-TGA? What are they?
There are 2 types of surgeries to repair d-TGA:
-Arterial Switch Operation: This is the most common surgery to treat d-TGA in which the MPA and Ao are switched and the coronary arteries are moved and reattached to the aorta.
-Atrial switch operation: This surgery is less commonly performed to treat d-TGA and it involves leaving the arteries are in place but creating a tunnel (baffle) between the atria. Even though this surgery is able to get some deoxygenated blood to the lungs and some oxygenated blood to the body, it may result in the RV having to pump harder than usual, making it possible for complications later on.
What may be needed after surgery? (1) What are they for? (4)
Medications may be needed after surgery in order to help the heart pump better, help get rid of extra fluid in the body, help decrease HR if there’s tachycardia, and control BP.
Infants who receive surgical repairs are not _____.
Infants who receive surgical repairs are not cured.
Infants who receive surgical repairs may have _____ _____.
Infants who receive surgical repairs may have lifelong conditions.
What will children and adults with d-TGA need?
Children and adults with d-TGA will need regular follow-up visits with a cardiologist.
Why are regular follow-up visits with a cardiologist necessary? (3)
Regular follow-up visits with a cardiologist monitor progress, avoid complications, and avoid other health conditions.
With proper _____, _____ babies with d-TGA grow up to lead _____, _____ lives.
With proper treatment, most babies with d-TGA grow up to lead healthy, productive lives.
Is d-TGA a critical CHD?
Yes
What is cyanosis?
Cyanosis is the condition of having bluish lips, skin, and nails because of low blood oxygen levels.
