Abstract

Objective This study evaluated the 2-year safety and effectiveness of the European First-in-Human INNOVATION trial for the INCRAFT AAA Stent Graft system (Cordis Corp, Bridgewater, NJ), an ultra-low-profile device for the treatment of abdominal aortic aneurysms. Methods From March 2010 to June 2011, the INNOVATION prospective multicenter trial involving six centers in Europe enrolled and treated 60 asymptomatic patients (95% male; mean age, 74.4 ± 6.9 years) with the INCRAFT System. Main inclusion criteria included proximal aortic neck length of 15 mm or more with a diameter up to 27 mm; distal iliac landing zones with a length greater than 10 mm and a diameter between 9 and 18 mm; and aortic bifurcation >18 mm in diameter and access vessels large enough to accept the 14F outer diameter of the delivery system. The primary end point was technical success at 1 month; 2-year safety end points included the absence of device- or procedure-related major adverse events, absence of type I or III endoleaks, and maintenance of device integrity through 2 years of follow-up. Study oversight was provided by a Data Safety Monitoring Board with event adjudication by a Clinical Events Committee and imaging analysis by an independent core laboratory. Results Of 60 successfully treated patients, two did not come back for their 1-month evaluation but remained enrolled in the study; 56 were evaluated at 1 year and 52 at 2 years. Of the 58 patients, 56 met the 1-month primary safety and effectiveness end point (97%; 95% confidence interval, 88%-100%). All patients were free from aneurysm enlargement through 2 years. There were no type I or III endoleaks at the 2-year time point. All-cause mortality at 2 years was 11.5%, and no death was device or procedure related. In total, three patients required a postprocedure intervention, two to repair a type I endoleak and one for limb occlusion. Core laboratory evaluation of the postoperative imaging studies documented absence of endograft migration and stent fractures in all patients. Conclusions The INCRAFT AAA Stent Graft System provides a durable solution for patients with abdominal aortic aneurysms, with a low frequency of device-related events through 2 years of follow-up.
