Key result
Direct epicardial mapping and ablation successfully terminated roof-dependent macroreentrant atrial tachycardia using the epicardial connection from the LA posterior to the Bachmann bundle.
Why the study?
Catheter ablation for macroreentrant AT recurring after AF ablation is occasionally difficult due to epicardial connections.
Does direct epicardial mapping and ablation improve procedural success in patients with recurrent macroreentrant atrial tachycardia after endocardial AF ablation?

Does direct epicardial mapping and ablation improve procedural success in patients with recurrent macroreentrant atrial tachycardia after endocardial AF ablation?
Direct epicardial mapping and ablation can successfully terminate complex roof-dependent macroreentrant atrial tachycardias utilizing epicardial connections to Bachmann's bundle.
No takes yet. Share an insight, caveat, or question.
May aid ablation of recurrent macroreentrant AT; leaves open the role of routine epicardial mapping.
Suzuki et al. (2025) conducted a case report in Recurrent macroreentrant atrial tachycardia after atrial fibrillation ablation (n=1). Direct epicardial mapping and ablation was evaluated on Termination of atrial tachycardia. Direct epicardial mapping and ablation successfully terminated roof-dependent macroreentrant atrial tachycardia using the epicardial connection from the LA posterior to the Bachmann bundle.
