Closure of the left atrial appendage to prevent strokes in atrial fibrillation patients

Left Atrial Appendage Closure Registry of Henri Mondor Hospital

Observational Assistance Publique - Hôpitaux de Paris · NCT05565209

This study is testing whether a procedure to close a small part of the heart can help people with atrial fibrillation reduce their risk of strokes instead of relying on long-term blood thinners.

What this trial studies

This observational study focuses on patients with atrial fibrillation who are at high risk of stroke due to thrombus formation in the left atrial appendage. It evaluates the long-term efficacy of a percutaneous left atrial appendage closure procedure, which involves implanting a device to prevent blood clots from causing strokes. The study will follow 150 patients over a period of five years to assess the outcomes of this intervention. The aim is to provide insights into the effectiveness of this procedure as an alternative to long-term anticoagulation therapy.

Who should consider this trial

Good fit: Ideal candidates include patients with atrial fibrillation who are indicated for left atrial appendage closure and are unable to take anticoagulants.

Not a fit: Patients who are minors, refuse participation, or are not affiliated with the French social security system may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the risk of stroke in patients with atrial fibrillation who cannot tolerate long-term anticoagulation.

How similar studies have performed: Other studies have shown promising results with left atrial appendage closure, indicating that this approach is gaining traction in clinical practice.
