Procedural characteristics and clinical outcomes from same-day discharge after pulsed field ablation treatment for atrial fibrillation: an admIRE trial sub-analysis

EuropacePublished

  • Secondary analysis of the admIRE trial

Authors' conclusion

SDD is feasible in a paroxysmal AF population undergoing PFA with the VLCC, demonstrating comparable safety and effectiveness outcomes with overnight hospitalization.

Study context

Population
Patients with paroxysmal atrial fibrillation (AF) undergoing pulsed field ablation (PFA) with a variable-loop circular catheter (VLCC)
Participants
277 patients
Comparison
Same-day discharge (SDD) vs overnight stays (ONS) after PFA
  • SDDn = 119
  • ONSn = 158reference
Primary endpoint
Freedom from composite failure:
  • Primary effectiveness
  • Kaplan-Meier
