Pulsed-Field Ablation of Atrial Tachycardia Originating From Bachmann's Bundle Via Epicardial Approach

Key Points

• To evaluate the efficacy of pulsed-field ablation (PFA) for atrial tachycardia originating from Bachmann's bundle.
• Utilized pulsed-field ablation via an epicardial approach.
• Compared outcomes with endocardial ablation cases.
• Assessed the impact of epicardial fat and tissue thickness on lesion depth.
• PFA successfully terminated atrial tachycardia in some cases.
• Recurrence of atrial tachycardia was noted, linked to the limits of lesion depth.
• Effectiveness of PFA may be reduced in thicker-walled tissues.
