Key result
The septal approach to atrial flutter ablation yielded similar fluoroscopy times (58.4 vs 70.8 minutes; P=0.7) and success rates as the posterior approach, but carried a higher risk of AV block.
Why the study?
Does the septal approach improve acute success rates or fluoroscopy times compared to the posterior approach for radiofrequency ablation of atrial flutter?
RCT (n=20)
randomized
Does the septal approach improve acute success rates or fluoroscopy times compared to the posterior approach for radiofrequency ablation of atrial flutter?
Absolute Event Rate: 58.4% vs 70.8%
p-value: p=0.7
The posterior approach is preferred for atrial flutter ablation due to a lower risk of atrioventricular block compared to the septal approach, with similar efficacy.
No takes yet. Share an insight, caveat, or question.
Avoid septal approach for atrial flutter ablation due to higher AV block risk; reinforces posterior as preferred with equivalent efficacy.
Passman et al. (2004) conducted an RCT in Atrial flutter (n=20). Septal approach to radiofrequency ablation vs. Posterior approach to radiofrequency ablation was evaluated on Acute success rates and fluoroscopy times (p=0.7). The septal approach to atrial flutter ablation yielded similar fluoroscopy times (58.4 vs 70.8 minutes; P=0.7) and success rates as the posterior approach, but carried a higher risk of AV block.
