Sex-Based Differences of Left Atrium: Impact on Atrial Fibrillation Ablation.
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.
Inclusion: 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: Previous cardiac ablation (including AF ablation or other arrhythmias); 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 < 18 years; Incomplete data regarding procedural parameters, or follow-up; Ablation not performed according to the BY-LAWT protocol.
