TGA - Transposition of the Great Arteries

What can be done to prevent the disease?

In most cases, nothing can be done to prevent TGA. A pregnant woman who has diabetes may be able to prevent TGA by controlling her blood sugar levels during pregnancy.

What are the long-term effects of the disease?

The long-term effects of TGA are related to the exact nature and severity of the heart defects. Children with TGA often have other heart defects. This can make treatment more complicated and reduce the chance of long-term survival. Death is common in those with TGA, especially when severe or complex defects of the heart are present. In those who undergo surgery, congestive heart failure may occur years later and cause disability or even death.

What are the risks to others?

TGA is not contagious and poses no risk to others.
