Key result
Radiofrequency ablation successfully eliminated recurrent left atrial macroreentrant tachycardia with a cycle length of 425 ms involving the Bachmann bundle in a 77-year-old man.
Why the study?
While bi-atrial tachycardia circuits commonly include the Bachmann bundle, few reports exist regarding its role in left atrial tachycardia circuits.
Case Report (n=1)
This case demonstrates that the Bachmann bundle can participate in left atrial macroreentrant tachycardia circuits, which can be successfully mapped and ablated.
No takes yet. Share an insight, caveat, or question.
Bachmann bundle mapping may be considered in left atrial macroreentry; leaves open confirmation in larger cohorts.
Yamaoka et al. (2022) conducted a case report in Recurrent atrial tachycardia (n=1). Radiofrequency ablation was evaluated on Inducibility of atrial tachycardia. Radiofrequency ablation successfully eliminated recurrent left atrial macroreentrant tachycardia with a cycle length of 425 ms involving the Bachmann bundle in a 77-year-old man.
