Summary

The single procedure success rates of durable pulmonary vein isolation (PVI) for paroxysmal atrial fibrillation (PAF) varies between 80 and 90 %.

This prospective, randomized study investigated the efficacy of pulmonary vein isolation with RF-energy following the CLOSE protocol with standard energy application (30 Watts) versus PVI with RF-energy with high power settings (45 Watts).

Conditions

  • Atrial Fibrillation Paroxysmal
  • Catheter Ablation

Interventions

OTHER

Pulmonary vein isolation

Comparison of power levels in catheter ablation in regard of single procedure success rate (freedom of any atrial arrhythmia with a duration of more than 30 sec. 45 Watts versus standard power levels (30 Watts).
