New stent graft could fix Life-Threatening aorta tears without open surgery
NCT ID NCT05800743
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a special tube called a stent graft to repair damage in the upper part of the main artery from the heart (the ascending aorta). It is for people with bulges (aneurysms), tears (dissections), or other lesions that usually need open-heart surgery. The goal is to see if the device can be placed safely and work well, avoiding the need for more procedures. About 370 participants will be enrolled.
