Key result
Atrial fibrillation ablation with transseptal puncture guided by intracardiac echocardiography was successfully performed in a patient with an interatrial septal occlusion device.
Why the study?
Interatrial septal occlusion devices hinder the transseptal approach for atrial fibrillation ablation, requiring imaging methods such as intracardiac echocardiography to safely guide transseptal puncture.
Case Report (n=1)
Intracardiac echocardiography can safely and effectively guide transseptal puncture for atrial fibrillation ablation in patients with interatrial septal occlusion devices.
May enable AF ablation via ICE-guided transseptal puncture in patients with septal occlusion devices; hypothesis-generating and requires prospective validation.
Interatrial septal occlusion devices hinder the transseptal approach for atrial fibrillation ablation, making it necessary to have imaging methods that safely guide transseptal puncture, such as intracardiac echocardiography (ICE). We describe the case of a 49-year-old patient with symptomatic paroxysmal atrial fibrillation, refractory to antiarrhythmic drugs, wearing an interatrial septal occlusion device, with a previous unsuccessful ablation attempt. Atrial fibrillation ablation was performed using the Carto V7 3D mapping system, the transseptal puncture was guided by ICE, and the procedure was successful. This case report highlights the importance of multimodality imaging to achieve successful and effective transseptal puncture for atrial fibrillation ablation in patients with interatrial septal occlusion devices.

Montesinos‐Segura et al. (2023) conducted a case report in Symptomatic paroxysmal atrial fibrillation with an interatrial septal occlusion device (n=1). Atrial fibrillation ablation with transseptal puncture guided by intracardiac echocardiography (ICE) was evaluated on Procedural success. Atrial fibrillation ablation with transseptal puncture guided by intracardiac echocardiography was successfully performed in a patient with an interatrial septal occlusion device.
