Video: The Arizona Heart Institute Announces the Largest Worldwide Experience with Endoluminal Grafting to Treat Thoracic Aortic Aneurysms and Related Pathologies
Date:9/28/2007

rysm, or "bulging" of the major artery which arises from the heart, is a serious condition prone to rupture and sudden death. According to the Society for Vascular Surgery, less than half of all patients who experience a rupture of a thoracic aortic die before reaching the hospital, making it the 13th leading cause of death in the U.S. Furthermore, studies report that emergent, open surgical repair of a ruptured thoracic aneurysm carries a 25 to 50 percent risk of death. ELGs, which are metal stents covered by a fabric graft material, offer a lower-risk alternative to open surgical repair. The device is delivered under X-ray guidance via a catheter passed through an artery near the groin. The ELG is then positioned and expanded within the aorta at the site of the problem, restoring blood flow, providing significant pain relief and reducing the risk of rupture. Depending on their general condition, patients typically return home within a few days.

"It is evident that ELGs represent an important means of treating thoracic aortic pathologies," said Venkatesh G. Ramaiah, M.D., study co-author and director of Peripheral Vascular and Endovascular Research at the Arizona Heart Institute. "To date, this is the largest published series of patients treated with thoracic ELGs for a variety of thoracic aortic pathologies. After more than 500 cases performed at the Arizona Heart Institute, complication rates, including death, compare favorably with open surgical repair, suggesting that endoluminal grafting is a favorable alternative in the treatment of thoracic aortic pathologies," said Ramaiah.

"We are very pleased with the results from this important study which further supports the movement toward minimally invasive management of aortic disease," said Edward B. Diethrich, M.D., medical director, founder of the Arizona Heart Institute and study author. "Since the early 1990s, we have pioneered a multitude of new technologies, treatments and therapies for cardiovasc
