Key result
Radiofrequency ablation terminates biatrial macro-reentrant tachycardia by targeting inter-atrial conduction.
Why the study?
Evidence on the potential role of septal inter-atrial muscular connections in re-entrant tachycardias is lacking.
Case Report (n=1)
Highlights the importance of recognizing epicardial and septal inter-atrial connections in complex biatrial tachycardias, especially post-extensive left atrial ablation.
No takes yet. Share an insight, caveat, or question.
May aid mapping of inter-atrial pathways in post-ablation tachycardias; hypothesis-generating and leaves broader applicability open.
Leandro et al. (2025) conducted a case report in Biatrial macro re-entrant tachycardia (n=1). Electrophysiological mapping and radiofrequency ablation was evaluated on Termination of tachycardia and non-inducibility. Radiofrequency ablation successfully terminated a biatrial macro re-entrant tachycardia utilizing Bachmann's bundle and septal inter-atrial connections.
