SAPIEN X4 Transcatheter Heart Valve for Failing Aortic Valves

This study is testing the safety and effectiveness of the SAPIEN X4/X4S Transcatheter Heart Valve (THV) in people whose existing aortic bioprosthetic valve is failing. You might be able to join if your current valve has moderate or worse narrowing (stenosis) or leaking (insufficiency), and your heart team believes surgery is too risky for you. The study will look at how many people experience death or stroke within one year after receiving the SAPIEN X4/X4S THV. This study aims to enroll about 200 participants, but its current recruitment status is unclear.

Study design
This is a single-arm study, meaning all participants will receive the SAPIEN X4/X4S THV. It is planned to include 200 participants across multiple centers.
What's involved
Not specified in the trial record.
Compensation
Not stated in the trial record.
Follow-up
The study will track participants for at least one year to measure outcomes like death and stroke.
