Atrial Fibrillation (AF)
Conditions
Brief summary
The aim of the study is to assess sex-related differences in patients who underwent a first ablation procedure for paroxysmal or persistent AF, guided by the personalized ablation strategy of the BY-LAWT protocol. Specifically, to compare anatomical characteristics, procedural parameters, and clinical outcomes between sexes.
Interventions
Atrial fibrillation ablation with RF, guided by navigation system

Eligibility
Inclusion criteria
* Patients who underwent a first ablation procedure for atrial fibrillation (paroxysmal or persistent). * Availability of an adequate pre-procedural cardiac CT scan for LAWT, LAV and inFAT analysis. * Availability of complete procedural data, including ablation index (AI) values recorded using the SmartTouch catheter (Biosense Webster). * Availability of 12-month follow-up data for efficacy and safety endpoint evaluation. * Ablation performed according to the by-LAWT protocol
Exclusion criteria
* Age \< 18 years. * Previous cardiac ablation (including AF ablation or other arrhythmias). * Incomplete data regarding procedural parameters, or follow-up. * Poor quality pre-procedural cardiac MDCT * Ablation not performed according to the BY-LAWT protocol. * Structural heart disease (e.g., dilated cardiomyopathy, valvular heart disease with surgical indication) that could substantially influence atrial dimensions or ablation response.

| Efficacy in AF freedom | from the procedure to 12 months later | The primary efficacy endpoint will be freedom from any atrial arrhythmia (AF, atrial tachycardia \[AT\], or atrial flutter \[AFL\]) at the 12-month follow-up. The following definitions apply |
