Nov 20, 2012– Minneapolis, USA (Techreleased) – Chosen for nearly one out of every two endovascular abdominal aortic aneurysm repairs worldwide, the Endurant AAA stent graft system from Medtronic, Inc. continues to show robust results in mid-term follow-up, according to two-year clinical data presented at VEITHsymposium, which concluded yesterday in New York.
The latest evidence on the market-leading stent graft comes from two clinical evaluations with two years of patient follow-up –– the U.S. investigational device exemption (IDE) study and the international ENGAGE registry, the largest collection of data on any single commercially available stent graft.
The U.S. IDE study of the Endurant system enrolled 150 patients at 26 U.S. centers and led to the device’s approval by the U.S. Food and Drug Administration (FDA) in December 2010. The international ENGAGE registry has enrolled more than 1,200 patients at more than 80 sites across six continents since the Endurant system received the CE (Conformité Européenne) mark in June 2008.
“It’s reaffirming to see that the two-year data from the international ENGAGE registry and the U.S. IDE study are similar to what we saw at one year, which indicates that the Endurant AAA stent graft continues to perform well in a variety of geographic locations and patient anatomies,” said ENGAGE investigator Dittmar Bockler, MD, PhD, of the University Hospital of Heidelberg in Germany, who shared these results at VEITHsymposium on Saturday. “The Endurant system sets a new standard in clinical outcomes for aortic stent grafts with unprecedented breadth, depth, quality and consistency of results.”
International ENGAGE Registry
Two-year results on 500 patients from the international ENGAGE registry showed that more than 98 percent (490 patients) were free from aneurysm-related mortality through two years of post-procedure follow-up. The Type I/III endoleak rate was low (1.1 percent) for this real-world patient population, with more than half (56 percent) of the aneurysm diameters among these 500 patients showing a reduction in size of 5 mm or more.
U.S. IDE Study
Demonstrating similar safety and efficacy, two-year results on all 150 patients from the U.S. IDE study showed 100 percent freedom from aneurysm-related mortality. Additionally, the Type I/III endoleak rate was low (0.8 percent), with more than three-fifths (62 percent) of the aneurysm diameters decreasing by at least 5 mm.
