Overview

Aortic root surgery is a procedure to treat an enlarged section of the aorta, also known as an aortic aneurysm. The aorta is the large blood vessel that carries blood from the heart to the body. The aortic root is where the aorta and the heart connect.

Aortic aneurysms near the aortic root may be due to an inherited condition called Marfan syndrome. Other causes include heart problems present at birth, such as a bicuspid aortic valve.

Ascending aortic root aneurysm procedure

An ascending aortic root aneurysm procedure may be done in two ways. Valve-sparing aortic root repair (top-right image) replaces the enlarged section of the aorta with an artificial tube, called a graft. The aortic valve stays in place. In aortic valve and aortic root replacement (bottom-right image), the aortic valve and a part of the aorta are removed. A graft replaces the section of the aorta. A mechanical or biological valve replaces the valve.
