Left atrial anatomy and atrial arrhythmia recurrence after pulsed-field ablation.
BACKGROUND The impact of left atrial (LA) anatomical features on atrial arrhythmia (AA) recurrence after pulsed-field (PF)-based pulmonary vein isolation (PVI) is unknown. This study aimed to assess LA anatomical features associated with long-term AA recurrence after PVI. METHODS We prospectively enrolled patients un...
