The Arizona Heart Institute announced today that results from its single-center study of the effectiveness of endoluminal grafting for thoracic aortic pathologies were published in the September 2007 issue of the Journal of Vascular Surgery. Presented in the leading subspecialty, peer-reviewed journal in the field of vascular surgery, the study showed that patients with potentially life-threatening conditions of the thoracic aorta, including thoracic aortic aneurysms, can be treated effectively using a less invasive method associated with minimal blood loss, faster recovery, shorter hospital stays and decreased risk of death.
