Key result
AF catheter ablation is linked to a ~1.5% acute complication rate and short-term symptom improvement.
Why the study?
The study was conducted to assess how clinical practice compares with current scientific evidence and quality indicators for AF ablation.

Does clinical practice for atrial fibrillation ablation in Portuguese centers align with current scientific evidence and quality indicators?
A national prospective registry demonstrates that atrial fibrillation ablation in Portugal is performed with a high standard of quality, aligning with current scientific evidence and yielding high rates of symptom improvement with low acute complications.
Supports AF ablation safety in Portugal; extends observational data while leaving randomized comparisons open.
Atrial fibrillation (AF) is the most common sustained arrhythmia, with significant burden for patients. Catheter ablation is safe and superior for symptom improvement. The purpose of this work was to assess how clinical practice compares with current scientific evidence and quality indicators for AF ablation. The Portuguese Association of Arrhythmology, Pacing and Electrophysiology conducted a prospective registry among Portuguese centers to assess clinical practice regarding management of patients referred for ablation and the methodology used in the procedures and related outcomes. A total of 337 patients were referred for ablation, 102 (37.91%) female, age 65 (56–70.8) years. The median CHADS 2 -VaSC 2 thromboembolic risk score was 2 (1–3), and 308 (92.49%) were on anticoagulants. AF was mainly paroxysmal (224, 66.97%) and symptomatic (mEHRA score 3; 2–3). Before ablation most patients (273, 81.49%) underwent cardiac computed tomography and only 24 (7.36%) procedures were performed with uninterrupted anticoagulation. For ablation, Carto® (194; 59.15%) and Ensite® (55; 16.77%) were mainly used, and the preferential strategy was pulmonary vein isolation (316; 94.61%). Acute complications occurred in five (1.49%) patients, while most had symptom improvement at one month (200; 86.21%), sustained at one year. There were 40 (12.6%) relapses within 30 days and 19 (26.39%) at one year. In a population of patients with AF referred for ablation in Portuguese centers, patient management is provided according to the best scientific evidence and there is a high standard of practice with respect to the quality of AF ablation practice. A fibrilhação auricular (FA) é a arritmia mantida mais comum, com ónus significativo sobre os doentes. A ablação por cateter é segura e superior para a melhoria sintomática. O objetivo deste trabalho é comparar a prática clínica com a evidência científica atual e indicadores de qualidade estabelecidos. Registo prospetivo conduzido pela Associação Portuguesa de Arritmologia, Pacing e Eletrofisiologia, em centros portugueses, avaliando a prática clínica na abordagem de doentes referenciados para ablação, metodologia utilizada e respetivos resultados. Foram referenciados 337 doentes, 102 (37,91%) do sexo feminino e idade 65 (56-70,8) anos. O risco tromboembólico era 2 (1-3), encontrando-se 308 (92,49%) sob hipocoagulação oral. Maioritariamente paroxística (224, 66,87%) e sintomática (mEHRA score 3; 2-3), previamente à ablação, a maioria (273, 81,49%) realizou TC cardíaca, com apenas 24 (7,36%) procedimentos realizados sem interrupção de hipocoagulação. Com uso predominante de sistema mapeamento Carto® (194; 59,15%) e Ensite® (55; 16,77%), a estratégia preferencial foi o isolamento das veias pulmonares (316; 94,61%). Ocorreram cinco complicações agudas (1,49%), tendo a maioria dos doentes melhoria sintomática no primeiro mês (200; 86,21%), mantida no primeiro ano. Aos 30 dias houve 40 (12,6%) recidivas, 19 após um ano (26,39%). Numa população de doentes com fibrilhação auricular referenciados para ablação em centros portugueses, a abordagem dos doentes está enquadrada na melhor evidência científica recomendada e existe um elevado padrão de qualidade no que concerne à prática do procedimento de ablação de FA.

Carmo et al. (2023) conducted an observational in Atrial fibrillation (n=337). Catheter ablation was evaluated on Acute complications. Catheter ablation for atrial fibrillation in Portuguese centers was associated with a 1.49% acute complication rate and 86.21% symptom improvement at one month.
