Children’s Health offers comprehensive care and treatment for all forms of congenital heart disease, no matter how rare. Physicians at Children’s Health are world-class subspecialists from UT Southwestern who provide advanced care for all forms of pediatric heart disease.
Transposition of the great arteries (TGA) is a rare congenital heart defect that happens when the “great arteries” are switched (transposed):
As a result, oxygen-rich blood flows from the heart to the lungs but not to the rest of the body. In other words, your child’s organs are not receiving enough oxygen to work properly.
Children born with TGA appear normal at first but as they adjust to life outside the womb, which includes maintaining their own blood flow, they will quickly become sick.
If your child’s condition was not diagnosed before they were born, we provide quick and accurate diagnosis once they start experiencing symptoms with the help of a physical exam and testing.
At Children’s Health, we perform diagnostic tests using special imaging equipment designed with our smallest patients in mind. Learn more about the full spectrum of tests available from our cardiac imaging department.
At Children’s Health, we deliver compassionate care that meets your child’s every need. From the moment your child is born, we are ready to deliver life-saving treatments.
Children’s Health delivers life-saving treatments for all forms of congenital heart disease, including TGA. Learn more about our cardiothoracic surgery program.
Here are answers to some frequently asked questions:
TGA occurs when the two “great arteries” – the pulmonary artery and the aorta – are switched (transposed).
TGA disrupts normal blood circulation, creating a closed loop that sends oxygen-rich blood back and forth from the heart to the lungs instead of out to the body and the brain.
TGA affects more boys than girls (two-thirds of TGA patients are boys). Genetic and environmental factors might play a role, but in many cases, there is no known cause.
Yes. Children with TGA struggle from the time they are born due to lack of oxygen. All children with TGA need open-heart surgery to repair the defect(s).
Some children will need ongoing care for complications such as an irregular heartbeat (arrhythmia), which can occur years after surgical repair.
