Patient group

People with severe aortic stenosis otherwise known as narrowing or constriction of their aortic valve may be eligible for this trial.

About this clinical trial

This study investigates the safety and efficacy of the Edwards 12F Sheath Introducer Set, a new and smaller sheath designed for transcatheter aortic valve replacement (TAVR) procedures. Researchers aim to determine whether the Edwards 12F Sheath can effectively deliver the Edwards SAPIEN X4 THV, a type of artificial aortic valve, while reducing the risk of vascular complications associated with TAVR. If successful, the Edwards 12F Sheath could offer a safer and more effective option for TAVR, improving the treatment of AS and potentially reducing the burden of this common valvular disease.
