Key result
Chemical ablation into the vein of Marshall may be a more beneficial treatment for biatrial tachycardia than Bachmann bundle ablation by avoiding interatrial conduction delay.
Why the study?
Biatrial tachycardia is rare with complicated re-entry circuit identification, and Bachmann bundle ablation risks interatrial conduction delay and left atrial appendage isolation.
Does chemical ablation into the vein of Marshall prevent interatrial conduction delay compared to ablation of the Bachmann bundle in patients with biatrial tachycardia?

Chemical ablation of the vein of Marshall may be preferable to Bachmann bundle ablation for treating biatrial tachycardia to avoid interatrial conduction delay.
Biatrial tachycardia (BiAT) is a rare arrhythmia, and identification of the re-entry circuit is often complicated. 1 By creating an activation map of the right atrium, left atrium, and coronary sinus as a single chamber, the Lumipoint module of the Rhythmia mapping system can be used in real time to make an accurate diagnosis. 2 Ablation of the Bachmann bundle is a feasible way to terminate BiAT, but might cause interatrial conduction delay and electrical isolation of the left atrial appendage. Chemical ablation into the vein of Marshall might be the more beneficial treatment, avoiding any potential interatrial conduction delay.

Yamashita et al. (2023) studied Biatrial tachycardia. Chemical ablation into the vein of Marshall vs. Ablation of the Bachmann bundle was evaluated. Chemical ablation into the vein of Marshall may be a more beneficial treatment for biatrial tachycardia than Bachmann bundle ablation by avoiding interatrial conduction delay.
