Brief summary (registry, in English)
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.

Who cannot take part
Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.
Prior treatment
- Previous cardiac ablation (including AF ablation or other arrhythmias).
Other illness
- Poor quality pre-procedural cardiac MDCT
- Structural heart disease (e.g., dilated cardiomyopathy, valvular heart disease with surgical indication) that could substantially influence atrial dimensions or ablation response.
Age
- Age \< 18 years.
Other
- Incomplete data regarding procedural parameters, or follow-up.
- Ablation not performed according to the BY-LAWT protocol.
Who the study is looking for
- 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
