Artery (Definition)

Arteries are a type of blood vessels. We can divide blood vessels into 2 categories. Arteries are high pressure vessels which deliver (red) oxygen + blood out into the body. Veins on the other hand or low pressure vessels which return (dark) oxygent - blood from the body ...Read more

Can you tell me about transposition of the great arteries?

Can you tell me about transposition of the great arteries?

Two main forms: Classic form (d-TGA) results in severe cyanosis (blue baby). The pulmonary artery arises from the left ventricle and the aorta arises from the right ventricle, resulting in 2 separate circulations in parallel--all the red, oxygenated blood returns to the lungs and the blue, deoxygenated blood goes to the body. Generally results in severe cyanosis and early death if not repaired in early infancy. ...Read more

What's the problem when a child has transposition of the great arteries?

Cyanosis: Cyanosis, or blue-tinged skin or mucous membranes, is caused by low oxygen levels in the blood (hypoxemia). In transposition of the great arteries, cyanosis is due to the aorta arising from the right ventricle (and the pulmonary artery arising from the left ventricle) which leads to de-oxygenated systemic venous blood being redirected to the body (and oxygenated blood recirculating in the lungs). ...Read more

Is it possible to be born with transposition of the great arteries?

Is it possible to be born with transposition of the great arteries?

Congenital: Transposition of the great arteries is a congenital heart defect, meaning that it is an abnormality of cardiac development and is fully present at birth. Classic, or d-tga refers to a disease where the aorta arises from the rv and the pulmonary artery arises from the lv. Diagnosis is typically made early. Another form of tga (l-tga) is a different disease where the rv and the lv are "inverted. ...Read more

It isn't until after birth, that this circulation changes and from "fetal blood circulation" to "adult blood circulation." often times, these babies will have heart surgery with in just a few days of being born and go on to live very normal lives. ...Read more

I'm curious, when a fetus has transposition of the great arteries are they unaffected until they are born?

I'm curious, when a fetus has transposition of the great arteries are they unaffected until they are born?

No: Usually fetuses tolerate the transposition hemodynamics very well in utero and after birth they will be cyanotic (blue). However, it is thought that transposition physiology may affect brain development because the blood with lower oxygen content is what supplies the fetal brain compared to fetuses with normal heart. In general, after repair transposition patient have excellent outcome. ...Read more
