Aortic Valve Stenosis study: Boston Scientific Sentinel
Official title CAPTURE-2: Controlled Arterial Protection to Ultimately Remove Embolic Material
ClinicalTrials.gov ID: NCT07276711
What this study is testing
- What it's testing
- This study aims to see if a special device is safe and works well to catch and remove blood clots or debris during a specific heart valve procedure.
- Who it's for
- People who have a narrow aortic valve and are scheduled to have a procedure to replace it with a new valve.
- What's involved
- Participants will have a heart valve procedure where a device is used to catch any loose material in the blood. Doctors will check if the device worked and if there were any problems.
- Time commitment
- The study involves the time needed for the heart valve procedure and follow-up checks to see how the device worked.
