Why the study?
Does right atrial ablation of complex fractionated atrial electrograms improve freedom from atrial fibrillation in patients with long-lasting persistent AF who remain in AF after left atrial ablation?
Does right atrial ablation of complex fractionated atrial electrograms improve freedom from atrial fibrillation in patients with long-lasting persistent AF who remain in AF after left atrial ablation?
Ablation of complex fractionated atrial electrograms in the right atrium provides no significant incremental efficacy over left atrial ablation alone in patients with long-lasting persistent atrial fibrillation.
No takes yet. Share an insight, caveat, or question.
Right atrial CFAE ablation adds no benefit after left atrial ablation in long-standing persistent AF; confirms lack of incremental efficacy and challenges its routine use.
Oral et al. (2008) studied this question.
