Key result
Radiofrequency catheter ablation for paroxysmal atrial fibrillation resulted in 43.5% of patients remaining completely free of atrial arrhythmias at a mean follow-up of 42.2 months.
Why the study?
Does radiofrequency catheter ablation provide long-term AF-free survival and symptomatic improvement in patients with paroxysmal AF?
Cohort (n=39)
Does radiofrequency catheter ablation provide long-term AF-free survival and symptomatic improvement in patients with paroxysmal AF?
Long-term follow-up shows that while catheter ablation for paroxysmal AF does not eliminate the arrhythmia in over half of patients, it provides symptomatic improvement in two-thirds.
No takes yet. Share an insight, caveat, or question.
May support symptomatic benefit despite incomplete arrhythmia control; leaves open need for randomized long-term outcome trials in paroxysmal AF.
Katritsis et al. (2008) conducted a cohort in Paroxysmal atrial fibrillation (n=39). Radiofrequency catheter ablation (pulmonary vein isolation) was evaluated on Freedom from AF or other atrial arrhythmia. Radiofrequency catheter ablation for paroxysmal atrial fibrillation resulted in 43.5% of patients remaining completely free of atrial arrhythmias at a mean follow-up of 42.2 months.
