Valor II: The Valiant Thoracic Stent Graft System Clinical Study
Study Details
Study Description
Brief Summary
This study was designed to study safety and effectiveness of the Valiant Thoracic Stent Graft to treat thoracic aortic aneurysms.
Condition or Disease | Intervention/Treatment | Phase |
---|---|---|

N/A |
Detailed Description
The aorta is a large blood vessel that carries blood away from the heart to the organs in the rest of the body. An aneurysm is a weakening in the artery wall that will become a bulge in the aorta. If left untreated, this bulge may continue to grow larger and may rupture (break open) with fatal consequences. In this research study we are investigating a device that can be placed in the aorta to exclude the weakened part of the artery wall and restore blood flow. Information will be collected on the performance of the device for 5 years.

Outcome Measures
Primary Outcome Measures
- Percentage of Participants That Did NOT Experience Aneurysm-Related Mortality (Post-market Primary Endpoint) [0 through 1825 days post treatment]
Evaluation of the ARM-free rate in subjects implanted with the Valiant Thoracic Stent Graft five years post-implantation by comparing it to a pre-defined performance goal (PG) based on an analysis of ARM-free rates from TEVAR data and on results from the VALOR (Talent Thoracic Endoluminal Stent Graft, IDE G980116) clinical study.
- Percentage of Participants With Successful Aneurysm Treatment (Primary Effectiveness Endpoint) [At 12-month post procedure]
Percentage of subjects with absence of both: a) aneurysm growth of more than 5 mm at the 12-month visit relative to the 1-month visit; and b) secondary procedure due to type I or III endoleak performed or recommended at or before the 12-month visit. Success means a subject experienced neither a nor b. Type I: endoleak in continuity with the proximal anchoring site(proximal endoleak) or the distal anchoring site(distal endoleak)of the device. Type III: endoleak is present in the mid-graft region due to defect of fabric or between the segments of the modular graft (junctional endoleak).
- Percentage of Participants Who Died (Primary Safety Endpoint: All-Cause Mortality) > > [Within 12-months post treatment]
The percentage of participants who died within 12-months of the initial procedure, whether or not the cause of death was related to the study device, procedure, or condition treated. > > Note: All-cause mortality endpoint is not directly related to successful aneurysm treatment, which pertains to the absence of aneurysm growth and secondary procedure due to Type I and III endoleaks.
