Zenith TX2LowProfile TAA Endovascular Graft: a next generation thoracic stent-graft.

AIM: The aim of the present article is to describe a new thoracic stent graft (Zenith TX2 Low-Profile TAA Endovascular Graft).

METHODS: Feasibility of endovascular repair of thoracic aortic aneurysms depends on several anatomic factors. A primary limitation is an adequate arterial approach. Since most currently used endografts require large introducer sheaths, patients with severely diseased iliofemoral vessels are often excluded from this less-invasive technique. Attempts to overcome access difficulties increase the risk for arterial access-site complications such as aortoiliac rupture. In addition, highly angulated proximal landing zones provide challenges in obtaining proximal graft conformance and sealing.

RESULTS: The introduction of next-generation endografts such as the Zenith TX2LowProfile TAA Endovascular Graft provides a solution for a larger number of patients, including those with small vessels, vascular access problems and tortuous aortic anatomy.

CONCLUSION: The ongoing Zenith TX2 Low-Profile Endovascular Graft trial will build further understanding of the performance of the device allowing for treatment of a wider patient population.
