Background
Use of the Frozen Elephant Trunk (FET) device to manage complex surgical pathologies of the aorta (such as acute Type A aortic dissection) has gained popularity since its introduction in the early 2000s. Though the distal anastomosis was traditionally performed at aortic Zone 3 (Z-3-FET), preference gradually shifted towards Zone 2 (Z-2-FET) in favour of improved surgical access and clinical outcomes. This review seeks to elucidate whether proximalisation of arch repair to Zone 0 (Z-0-FET) would further improve postoperative outcomes.
