Abstract
Endovascular therapies have had a considerable impact on contemporary management of thoracic aortic disease. Still, with the anatomic challenges of the aortic arch, endovascular experience with devices that traverse the arch and deploy in the Zone 0 position remains limited. We report the first Canadian experience with the RelayBranch Thoracic Stent Graft (Terumo Aortic, Sunrise, FL) with Zone 0 deployment for total endovascular aortic arch repair in a patient at very high risk for redo open surgery. We demonstrate safe deployment of the device and successful treatment of a type 1A endoleak. Features of the RelayBranch design that mitigate challenges of arch deployment are also discussed.
