Left atrial appendage closure with AtriLASH Seralene suture during cardiac surgery for atrial fibrillation

Left Atrial Appendage Closure During Cardiac Surgery in Atrial Fibrillation Patients With Seralene

Not applicable Interventional Institute of Cardiovascular Diseases, Vojvodina · NCT07360899

This trial tests whether closing the left atrial appendage with the AtriLASH Seralene hemostatic suture during cardiac surgery can reduce stroke risk in adults with atrial fibrillation.

What this trial studies

Adults with documented atrial fibrillation and elevated stroke risk who are already scheduled for cardiac surgery will have the left atrial appendage closed using the AtriLASH Seralene hemostatic suture during their operation. The study enrolls patients with CHA2DS2-VASc scores of 2 or greater and excludes those with LAA thrombus, unsuitable anatomy, active endocarditis, or very limited life expectancy. Outcomes will focus on perioperative safety and the effectiveness of achieving durable LAA closure to reduce thromboembolic events. Follow-up will monitor surgical complications, device performance, and stroke or bleeding outcomes.

Who should consider this trial

Good fit: Adults (18+) with any type of atrial fibrillation, a CHA2DS2-VASc score ≥2, and who are scheduled for cardiac surgery are ideal candidates.

Not a fit: Patients with left atrial appendage thrombus, anatomies unsuitable for the device, active infective endocarditis, or very limited life expectancy are unlikely to benefit from this procedure.

Why it matters

Potential benefit: If successful, this approach could lower stroke risk for surgical patients with atrial fibrillation and offer an option for those who cannot take long-term blood thinners.

How similar studies have performed: Surgical left atrial appendage closure has prior supportive data with other techniques, but use of the AtriLASH Seralene hemostatic suture is relatively novel and not yet widely tested.
