Aortic root surgery is a complex surgical procedure to treat dilation or aortic enlargement (aneurysm) of a section of the large blood vessel that carries blood from your heart to your vital organs (aorta). The aortic root is located near the junction of your aorta and your heart.

Doctors perform aortic root surgery to prevent an aneurysm rupture or a tear in the inner layer of the wall of the dilated aorta (aortic dissection), and to prevent the dilated aorta from stretching the attached aortic valve.

Aortic aneurysms near the aortic root may be associated with Marfan syndrome and other heart or genetic conditions.

Your doctor will discuss with you the most appropriate treatment or surgery for your individual condition and discuss the benefits and risks of surgery. Your doctor will also evaluate your risk of aortic dissection and measure the diameter of your aorta when deciding if you are a candidate for surgery.
