Key result
Epicardial RF ablation at Bachmann's bundle terminates recurrent biatrial macroreentrant tachycardia in a single patient.
Why the study?
Recent reports have highlighted the role of epicardial connections in the development of biatrial tachycardia circuits.
Does epicardial mapping and ablation via Bachmann's bundle terminate biatrial macroreentrant tachycardia in a patient with recurrent AT?

Does epicardial mapping and ablation via Bachmann's bundle terminate biatrial macroreentrant tachycardia in a patient with recurrent AT?
Epicardial mapping and ablation of Bachmann's bundle can effectively identify and terminate biatrial macroreentrant atrial tachycardia circuits.

May support epicardial Bachmann's bundle targeting in refractory biatrial tachycardia; hypothesis-generating and requires prospective validation before practice change.
Yorgun et al. (2023) conducted a case report in Recurrent atrial tachycardia (n=1). Epicardial mapping and radiofrequency ablation was evaluated on Termination of atrial tachycardia. Epicardial radiofrequency ablation at the Bachmann's bundle region successfully terminated recurrent biatrial macroreentrant tachycardia in a 60-year-old female patient.
