JAMA Cardiology 10.1001/jamacardio.2026.0336March 25, 2026 at 11:00 AM EDT
What are the implications of major bleeding after left atrial appendage occlusion in the Amulet IDE trial?In this study, major bleeding occurred primarily within the first 6 months, driven by periprocedural factors and intensive antithrombotic therapy, then declined as therapy is reduced. Predictors are patient-specific—older age, female sex, diabetes, prior bleeding, and kidney disease, and major bleeding was linked to higher rates of stroke and mortality.These results highlight the need for individualized bleeding-risk assessment, careful antithrombotic management, optimized procedural safety, and vigilant postimplant monitoring, as early bleeding is common and associated with worse outcomes.
