Atrial Arrhythmias Following Surgical AF Ablation: Electrophysiological Findings, Ablation Strategies, and Clinical Outcome
Key result
Radiofrequency catheter ablation guided by 3D mapping successfully treated recurrent atrial tachycardias, leaving 87% of patients free of atrial arrhythmias at 18 months.
Why the study?
Does radiofrequency catheter ablation improve freedom from atrial arrhythmias in patients with symptomatic recurrence of atrial arrhythmias following intraoperative AF ablation?

Structured PICO
Does radiofrequency catheter ablation improve freedom from atrial arrhythmias in patients with symptomatic recurrence of atrial arrhythmias following intraoperative AF ablation?
P
Population
82 patients (48 male, median age of 65 years) with symptomatic recurrence of atrial arrhythmias following intraoperative atrial fibrillation ablation
I
Intervention
Radiofrequency catheter ablation guided by 3-dimensional (3D) color-coded entrainment/activation mapping
O
Outcome
Freedom from atrial arrhythmias
Radiofrequency catheter ablation guided by 3D mapping is highly effective for treating symptomatic atrial arrhythmia recurrences after surgical AF ablation, achieving 87% freedom from arrhythmias at 18 months.
Cite This Study
Huo et al. (2014) conducted a cohort in Symptomatic recurrence of atrial arrhythmias following intraoperative AF ablation (n=82). Radiofrequency catheter ablation guided by 3D mapping was evaluated on Freedom from atrial arrhythmias. Radiofrequency catheter ablation guided by 3D mapping successfully treated recurrent atrial tachycardias, leaving 87% of patients free of atrial arrhythmias at 18 months.
