Electrophysiological studies in a 70-year-old man with atrial tachycardia revealed that Bachmann's bundle served as an epicardial bypass within the tachycardia circuits.
Case Report (n=1)
This case demonstrates that Bachmann's bundle can serve as an epicardial bypass in the development of atrial tachycardias in a remodeled left atrium.
A 70-year-old man with a history of prior ablation for atrial fibrillation presented with atrial tachycardia (AT). Electrophysiological studies revealed roof-dependent and localized-reentrant ATs. During each AT, widespread breakthrough activation was observed just anterior to the low-voltage area on the anterior wall, suggesting that Bachmann's bundle served as an epicardial bypass within the tachycardia circuits. This case highlights the potential role of Bachmann's bundle in the development of ATs in the remodeled left atrium.
Sakurai et al. (Wed,) conducted a case report in Atrial tachycardia (n=1). Electrophysiological studies was evaluated on Identification of tachycardia circuits. Electrophysiological studies in a 70-year-old man with atrial tachycardia revealed that Bachmann's bundle served as an epicardial bypass within the tachycardia circuits.
