Comparing LAA closure and anticoagulation for atrial fibrillation patients after brain bleeding

Official title: Randomized Comparison of Interventional Closure of the Left Atrial Appendage Using a LAA Closure Device Versus Oral Anticoagulation Therapy in Patients With Non-valvular Atrial Fibrillation and Status Post Intracranial Bleeding.

Run by Jena University Hospital · NCT04298723 · Data updated 2026-11-12

This study is testing whether closing a part of the heart or using blood thinners is better for preventing strokes in patients with atrial fibrillation who have had a brain bleed.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older with documented atrial fibrillation and a history of intracranial bleeding more than six weeks prior.

Probably not a fit

Patients with significant comorbidities requiring ongoing anticoagulation therapy or those with active infections or severe liver failure may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial compares two treatment options for patients with atrial fibrillation who have experienced an intracranial bleed. It evaluates the effectiveness of left atrial appendage (LAA) closure versus oral anticoagulation therapy in preventing strokes. The study involves a randomized approach, using already approved drugs and devices, to assess the safety and efficacy of these interventions. The goal is to generate data that could inform clinical guidelines for managing these high-risk patients.

Why it matters

Potential benefit: If successful, this study could provide a safer treatment option that reduces the risk of bleeding while effectively preventing strokes in patients with atrial fibrillation.

How similar studies have gone: While there is existing evidence supporting both treatment approaches, this specific comparison in patients post-intracranial bleeding is novel and has not been extensively tested.
