Current state and future directions of endovascular ascending and arch repairs: The motion towards an endovascular Bentall procedure

Endovascular repair of the ascending aorta and aortic arch has evolved at an astonishing pace in the past several decades. Results of endovascular arch repair in experienced cen-ters have been improving and the technology evolving, and it has begun to challenge the current gold standard status of open surgery in some groups of patients. Hybrid strategies with adjunctive cervical debranching for distal arch lesions are being replaced by fenes-trated arch repairs. Total endovascular repair for proximal aortic arch pathologies with the use of inner branches has achieved the best results; however, the main current limitations of endovascular arch repair are diameter-, length-, and angulation-related issues with the ascending aorta (proximal landing zone). Ascending aorta endovascular repair has allowed extending treatment further proximally in patients with post-surgical pseudoaneurysms of the ascending aorta or post-type A chronic aortic dissections. However, sufficient proximal landing zone is still needed in the proximal aorta for these repairs; in a significant number of patients, this is not feasible with simple proximal tubular grafts. Therefore, new tech-nologies and techniques are being developed to deal with this limitation, including the en-dovascular Bentall concept, with incorporation of the aortic valve and coronary ostia. In this review, the current state and future directions of endovascular ascending and arch repairs and the motion towards an endovascular Bentall procedure are discussed.(c) 2022 Elsevier Inc.
