In most cases, transposition of the great arteries can't be prevented. If you have a family history of heart defects or if you already have a child with a congenital heart defect, before getting pregnant consider talking with a genetic counselor and a cardiologist experienced in congenital heart defects.
Additionally, it's important to take steps to have a healthy pregnancy. For example, before becoming pregnant, be sure you're up to date on all of your immunizations, and start taking a multivitamin with 400 micrograms of folic acid.
