What is it?

Transposition of the great arteries (TGA) is a congenital heart defect characterized by reversed arteries leaving the heart. In a complete transportation, or dextro- transposition, the aorta and the pulmonary artery have switched positions, thus, blood rich with oxygen cannot reach the body cells, causing symptoms during pregnancy or right after birth. This condition must be corrected to avoid complications. Risk factors include history of rubella or viral illness during pregnancy, drinking alcohol or taking certain drugs during pregnancy, smoking and a poorly controlled maternal diabetes.
