Key result
Septal atrial tachycardia has distinct electrophysiologic characteristics compared to free-wall AT, but radiofrequency ablation yields similar recurrence rates (3.2% vs 4.6%, P=0.08).
Why the study?
Does radiofrequency ablation have different success and recurrence rates for septal versus free-wall atrial tachycardias in patients with AT?
Cohort (n=141)
Does radiofrequency ablation have different success and recurrence rates for septal versus free-wall atrial tachycardias in patients with AT?
Absolute Event Rate: 3.2% vs 4.6%
p-value: p=0.08
Septal atrial tachycardias have distinct electrophysiologic characteristics compared to free-wall ATs, but radiofrequency ablation is equally safe and effective for both locations.
No takes yet. Share an insight, caveat, or question.
Similar RFA recurrence rates for septal and free-wall AT support uniform ablation approaches; leaves open need for prospective validation.
CHEN et al. (2000) conducted a cohort in Atrial tachycardia (n=141). Septal atrial tachycardia vs. Free-wall atrial tachycardia was evaluated on Recurrence rate (p=0.08). Septal atrial tachycardia has distinct electrophysiologic characteristics compared to free-wall AT, but radiofrequency ablation yields similar recurrence rates (3.2% vs 4.6%, P=0.08).
