Reoperative Repair of Aortic Root and Ascending Aorta

摘要

Aneurysms involving the ascending aorta and aortic root can be repaired with low operative risk. Operations such as composite valve-graft root replacement or valve-sparing root reconstruction carry expected mortality <4% with few perioperative complications. However, reoperative surgery on the ascending aorta continues to be quite challenging for cardiac surgeons. The mortality for these complex reconstructions is routinely 3 times higher than with elective surgery and often associated with substantial morbidity.
