  • Many cases of ascending thoracic aortic aneurysms are associated with an underlying bicuspid aortic valve. (ahajournals.org)

  • Aneurysms in the ascending aorta may require surgery at a smaller size than aneurysms in the descending aorta. (wikipedia.org)
  • Open aortic surgery is distinct from aortic valve repair and aortic valve replacement, as OAS describes surgery of the aorta, rather than of the heart valves. (wikipedia.org)
  • Disease of the aorta proximal to the left subclavian artery in the chest lies within the specialty of cardiac surgery, and is treated via procedures such as the valve-sparing aortic root replacement. (wikipedia.org)
  • In 2003, EVAR surpassed open aortic surgery as the most common technique for repair of AAA, and in 2010, EVAR accounted for 78% of all intact AAA repair in the United States. (wikipedia.org)
