Key Result

Left atrial appendage occlusion device implantation in AF patients with CHA2DS2-VASc <3 resulted in lower complications and hospitalization costs.

Key Points

  • This research aims to compare outcomes of left atrial appendage occlusion in atrial fibrillation patients with lower stroke risk.
  • Analyzed outcomes of patients with CHA2DS2-VASc < 3
  • Assessed complications and hospitalization costs after LAAO device implantation
  • Evaluated potential implications for clinical practices in stroke prevention
  • Patients with lower CHA2DS2-VASc scores experienced fewer complications
  • Hospitalization costs were also lower for these patients
  • Findings suggest the need for further validation in a larger trial

Structured PICO

Does left atrial appendage occlusion device implantation result in lower complications and costs in atrial fibrillation patients with lower stroke risk (CHA2DS2-VASc < 3)?

P
Population
Atrial fibrillation patients undergoing left atrial appendage occlusion (LAAO) device implantation, specifically focusing on those with lower stroke risk (CHA2DS2-VASc < 3).
I
Intervention
Left atrial appendage occlusion (LAAO) device implantation
C
Comparator
Atrial fibrillation patients with higher stroke risk (CHA2DS2-VASc ≥ 3) undergoing LAAO
O
Outcome
Complications and hospitalization costssafety

LAAO device implantation in atrial fibrillation patients with lower stroke risk (CHA2DS2-VASc < 3) is associated with lower complications and hospitalization costs, suggesting potential clinical implications for stroke prevention in this subgroup.

Limitations

  • Findings need to be redemonstrated in a large randomized trial

Abstract

Patients with CHA2DS2-VASc < 3 had lower complications and hospitalization costs after LAAO device implantation. These data, if redemonstrated in a large randomized trial, can have important clinical implications for stroke prevention in AF patients.
