简要总结
The HERCULES trial is a Randomized controlled clinical trial designed to prospectively compare endosuture aneurysm repair (ESAR) to standard endovascular aneurysm repair (EVAR) clinical outcomes in treatment of infrarenal abdominal aortic aneurysm (AAA) in subjects having wide proximal aortic neck diameters (≥ 28mm and ≤ 32mm).
详细描述
HERCULES is an investigator driven trial and a collaborative research project with Medtronic.
Design; Prospective, post-market, global, multicenter, randomized (1:1), two-arm, superiority trial
Up to 300 subjects will be recruited in up to 40 sites in Europe and the US. All subjects shall be followed per local societal guidelines and per the Endurant II/IIs and Heli-FX EndoAnchor instruction for use (IFU) recommendations for post-implant follow-up and CT-imaging, with expected assessments at baseline, index procedure(s), 1-month, and annually at 1, 2, 3, 4, and 5 years post-index procedure.
Devices used in HERCULES include the Endurant II/IIs stent graft system (EVAR arm) and the Endurant II/IIs stent graft system plus the Heli-FX EndoAnchor System (ESAR arm)
This study is being conducted to collect clinical evidence from treatment of patients with infrarenal AAA having wide proximal aortic neck diameters (≥ 28mm and ≤ 32mm), comparing clinical outcomes with treatment of the AAA with the Endurant II/IIs stent graft in conjunction with Heli-FX EndoAnchors to treatment of the AAA with the Endurant II/IIs stent graft alone. Though both the Endurant II/IIs stent graft and Heli-FX EndoAnchors are commercially approved in this indication, clinical evidence comparing these two treatments in patients with wide proximal aortic neck diameters is not currently available. Collecting clinical data specific to this patient population, including procedure and imaging data as well as long term outcomes, will provide a foundation to further characterize the clinical outcomes of treatment for patients with infrarenal AAA with wide proximal aortic neck diameters.

结局指标
主要结局
Composite endpoint at on proximal seal outcomes
时间窗: 1 year follow-up
The primary endpoint is a composite endpoint based on core lab reported data from computed tomography (CT) with contrast imaging of freedom from: 1. type IA endoleak and 2.

- Freedom from type IA endoleak(1 year follow-up)
- Freedom from aneurysm sac growth(1 year follow-up)
- Freedom from neck dilatation ≥ 3 mm(1 year follow-up)
