Percutaneous Left Atrial Appendage Occlusion: How Much Do We Know?

CBSMD

Pre-reading

  • Definition of percutaneous left artrail appendage occlusion
  • Indications for LAAO therapy

  • How to define study endpoints, stroke and classifications, transient ischemic attack, cardiovascular mortality, non-cardiovascular mortality, procedural mortality, immediate procedural mortality, systemic embolism, pericardial effusion, bleeding events etc.  




RCTs


Year 2009, "Percutaneous closure of the left atrial appendage versus warfarin therapy for prevention of stroke in patients with atrial fibrillation: a randomised non-inferiority trial"

confirmed the efficacy of percutaneous closure of the LAA with this device was non-inferior to that of warfarin therapy. Although there was a higher rate of adverse safety events in the intervention group than in the control group, events in the intervention group were mainly a result of periprocedural complications. Closure of the LAA might provide an alternative strategy to chronic warfarin therapy for stroke prophylaxis in patients with non-valvular atrial fibrillation.
