Key result
Epicardial RF ablation at Bachmann's bundle terminates recurrent LA macroreentrant tachycardia after failed endocardial ablation.
Why the study?
Data regarding the feasibility and effectiveness of epicardial ablation for recurrent atrial tachycardia despite successful termination from an endocardial site are scarce.
Population
A 65-year-old female patient with recurrent left atrial macroreentrant tachycardia after endocardial ablation

May be considered for refractory left atrial macroreentry after endocardial failure; leaves open need for prospective validation.
Case Report (n=1)
Epicardial mapping and ablation at the Bachmann's bundle region can successfully terminate recurrent left atrial macroreentrant tachycardia when endocardial ablation is insufficient.
Yorgun et al. (2021) conducted a case report in Recurrent left atrial macroreentrant tachycardia (n=1). Epicardial mapping and ablation was evaluated. Epicardial radiofrequency ablation at the Bachmann's bundle region successfully terminated recurrent left atrial macroreentrant tachycardia (cycle length 370 ms) after failed endocardial ablation.
