This covers a major open-heart surgery to repair or replace a damaged section of the body's main artery near where it curves at the top of the heart, known as the aortic arch. The operation is performed with the heart temporarily stopped and blood circulated by a heart-lung bypass machine while the repair is made. This is a high-complexity operation typically reserved for conditions such as an aneurysm or tear in this part of the aorta.
