This study tests a new way to help prevent strokes in people having heart surgery. Stroke is when blood flow to the brain stops, causing brain damage. The study involves a procedure called **Left Atrial Appendage Exclusion (LAAE)**, which closes off a part of the heart to stop blood clots from forming, which could lead to strokes. This study is for people 18 or older with certain heart risks.
Key Points:
- Duration & Visits: Participation requires regular check-ups during and after heart surgery.
- Eligibility: Participants must not have had specific heart procedures before or have certain health conditions.
- Risks & Benefits: The procedure may reduce stroke risk, but risks include surgery-related complications.
Participants can't have had heart rhythm problems known as **atrial fibrillation** (an irregular heartbeat) lasting 6 minutes or more, or certain infections, allergies, or other severe health issues. The study is blinded, meaning participants and doctors won't know who gets the new procedure or not, to ensure fair results. If you meet the criteria and decide to join, you'll help explore a potential new way to reduce stroke risk during heart surgeries.
