Proven clinical track record — five-year outcomes in all descending thoracic aortic pathologies.
Review the results with Valiant Captivia clinical trials:
Five-year outcomes
The VALOR II Valiant™ Thoracic Stent Graft System Pivotal Study1 was designed to evaluate the safety and effectiveness of the Valiant™ thoracic stent graft in the treatment of fusiform thoracic aortic aneurysms, saccular aneurysms, and penetrating aortic ulcers of the descending thoracic aorta.

The Medtronic Dissection Trial was designed to evaluate the safety and effectiveness of the Valiant™ thoracic stent graft in the treatment of acute, complicated Type B dissection, as determined by all-cause mortality within 30 days of the index procedure, compared to a performance goal based on TEVAR and open surgical repair outcomes.
The primary endpoint for this trial was all-cause mortality within 30 days of the index procedure. The Medtronic Dissection Trial met its primary endpoint with a 30-day all-cause mortality rate of 8.0% (4/50).†‡§ Four (4) subjects died within 30 days of the index procedure.
The Valiant™ Captivia™ thoracic stent graft system effectively treated acute complicated Type B aortic dissections with positive aortic remodeling through five years.

The Valiant™ Captivia™ system effectively treated acute complicated Type B aortic dissections with positive aortic remodeling through five years.
The RESCUE trial was designed to evaluate the clinical performance of the Valiant™ thoracic stent graft for treatment of blunt thoracic aortic injury (BTAI).
The primary endpoint for this study included all enrolled subjects and was measured by the all-cause mortality rate within 30 days. Four subjects died within 30 days of the index procedure. This result demonstrated a 30-day all-cause mortality rate of 8.0% (4/50) for BTAI subjects treated with the Valiant™ thoracic stent graft.
Excellent five-year outcomes and durable exclusion of BTAI

There were no Type I or Type III endoleaks reported in this study population. There were two subjects reported to have a Type II endoleak at the end of procedure by the site; both of these endoleaks resolved without treatment by the one-month visit. No technical observations were reported from the one-month follow-up CTA/MRA images. The stent graft integrity was maintained in 100% of the cases. There were no reports of stent graft twisting, kinking, or fracture, and all stent grafts remained patent as reported by the sites and the core lab. There were no occurrences of unanticipated adverse device effects (UADEs) in this trial.

† Based on the number of evaluated subjects. Subjects will be considered unevaluable if they are withdrawn before the lower limit of the 30-day follow-up window (16 days) or if they are lost to follow-up before the lower limit of the 30-day follow-up window (16 days) and had no contact thereafter.
