Closure of the left atrial appendage in patients with atrial fibrillation and severe kidney disease

Prospective, Randomized, Controlled, Unblinded, International, Multicentre, Parallel Two Group Trial of Left Atrial Appendage Closure in Patients With Non-valvular Atrial Fibrillation and End-stage

Not applicable Interventional University of Luebeck · NCT05204212

This study is testing if using a special device to close a part of the heart can help people with atrial fibrillation and severe kidney disease have fewer strokes and bleeding problems compared to standard medical treatments.

What this trial studies

This trial evaluates the effectiveness of left atrial appendage (LAA) closure devices compared to best medical care in patients with non-valvular atrial fibrillation (NVAF) who also have end-stage kidney disease (ESKD). Participants will be randomly assigned to receive either the LAA closure device or standard medical therapies, including anticoagulants and antiplatelet agents. The study aims to determine if LAA closure can reduce the risk of stroke and bleeding in this high-risk population. The devices being tested include the Amplatzer Cardiac Plug and Amulet, which are already clinically used.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with documented NVAF and end-stage renal disease.

Not a fit: Patients with contraindications to anticoagulation therapy or other significant comorbidities may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the risk of stroke and bleeding in patients with atrial fibrillation and severe kidney disease.

How similar studies have performed: While there have been studies on LAA closure in general, this specific approach in patients with ESKD is novel and has not been extensively tested.
