Why it's done

Doctors perform aortic root surgery to prevent a burst aneurysm. They also perform it to prevent a tear in the inner layer of the aorta's wall (aortic dissection). They also do it to prevent the enlarged aorta from stretching the attached aortic valve. Aortic aneurysms near the aortic root may be related to Marfan syndrome and other heart or inherited conditions.
