The Horizon stent graft showed high procedural success and safety in a 1-year follow-up of two trials. No major adverse events occurred during follow-up, meeting primary safety and performance endpoints.
Area of Science:
- Vascular Surgery
- Medical Devices
- Clinical Trials
Background:
- Abdominal aortic aneurysms (AAAs) are a significant cause of mortality.
- Endovascular aneurysm repair (EVAR) offers a less invasive treatment option.
- New stent graft systems aim to improve safety and efficacy.
Purpose of the Study:
- To evaluate the 1-year follow-up results of the Horizon stent graft system.
- To assess the safety and performance of the Horizon stent graft in prospective trials.
Main Methods:
- Analysis of data from 40 patients across a first-in-man (FIM) and a pivotal study.
- Outcomes included freedom from major adverse events (MAEs) and device performance.
- MAEs encompassed mortality, MI, renal failure, stroke, and more.
Main Results:
- 39 out of 40 procedures were successful in device delivery and deployment.
- No major adverse events were registered during the 1-year follow-up.
- Two deaths and one aneurysm growth occurred, unrelated to endoleak.
Conclusions:
- The Horizon stent graft met primary safety and performance endpoints.
- The device demonstrated successful delivery and deployment in the majority of cases.
- No major adverse events were observed during follow-up, indicating a favorable safety profile.

Guidelines for Writing Outcome
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...
