Summary

Assessing the impact of a new atrial fibrillation (AF) catheter ablation energy on left atrial structure and function is of crucial importance.

The goal of this clinical trial is to assess the effect of pulsed-field ablation of atrial fibrillation on left atrial structure.

Conditions

  • Persistant Atrial Fibrillation
  • Paroxysmal AF

Interventions

PROCEDURE

Atrial fibrillation ablation procedure planned using pulsed-field ablation and including at least pulmonary vein isolation and posterior wall isolation

Persistent or paroxysmal atrial fibrillation treated by pulse-field ablation. Interventions added by the study are cardiac MRI (pre-ablation and 4 months after ablation) with administration of contrast agent (Dotarem®).
