Advanced Disease Arm: To collect data on consecutively treated patients, the Advanced Disease Arm will be comprised of subjects that required placement of EndoAnchors proximal to the LCCA or in the visceral segment of the aorta distal to the celiac artery and proximal to the renal arteries. Subjects with thoracic procedures which require arch vessel transposition(s) or bypass (except to the left subclavian artery) or hybrid open-endovascular procedures as well as those with abdominal or thoracic procedures that require chimney procedures into any renal or visceral artery should also be included in the Advanced Disease arm.
