Objetivos: Avaliar a preval\u00eancia e os fatores associados \u00e0 FA cl\u00ednica e \u00e0 FA induzida durante o estudo eletrofisiol\u00f3gico (EEF) em uma grande coorte consecutiva de pacientes com WPW submetidos \u00e0 abla\u00e7\u00e3o de via acess\u00f3ria (VA).  M\u00e9todos: Esta an\u00e1lise retrospectiva incluiu 845 pacientes consecutivos com WPW submetidos \u00e0 abla\u00e7\u00e3o de VA em um \u00fanico centro terci\u00e1rio de refer\u00eancia. Um protocolo padronizado de EEF foi aplicado durante todo o per\u00edodo do estudo. Os desfechos inclu\u00edram FA cl\u00ednica (documentada por hist\u00f3rico m\u00e9dico ou monitoriza\u00e7\u00e3o antes do EEF), FA induzida no EEF e qualquer FA (desfecho composto). Modelos de regress\u00e3o log\u00edstica multivari\u00e1vel foram utilizados para estimar odds ratios ajustados (ORa) com intervalo de confian\u00e7a de 95% (IC 95%). A signific\u00e2ncia estat\u00edstica foi definida como p &lt; 0,05.  Resultados: A m\u00e9dia de idade foi de 33,2 \u00b1 15,9 anos, e 486 dos 845 pacientes (57,5%) eram do sexo masculino. M\u00faltiplas VAs foram identificadas em 31 pacientes (3,7%). As localiza\u00e7\u00f5es mais comuns das VAs foram lateral esquerda (327\/845, 38,7%) e posterior (323\/845, 38,2%). FA cl\u00ednica esteve presente em 109 pacientes (12,9%), FA induzida no EEF em 77 (9,1%) e qualquer FA em 168 (19,9%). Nas an\u00e1lises multivari\u00e1veis, uma VA lateral esquerda esteve independentemente associada \u00e0 FA cl\u00ednica (ORa, 2,31; intervalo de confian\u00e7a de 95% [IC 95%], 1,53-3,49; p &lt; 0,001), enquanto uma VA posterior esteve associada \u00e0 FA induzida no EEF (ORa, 1,78; IC 95%, 1,07-2,91; p = 0,025). O sexo feminino esteve associado a menores chances de FA induzida no EEF (ORa, 0,56; IC 95%, 0,34-0,93; p = 0,025). O aumento da idade esteve independentemente associado \u00e0 FA cl\u00ednica (ORa por ano, 1,018; p = 0,007) e a qualquer FA (ORa por ano, 1,014; p = 0,009).  Conclus\u00e3o: Nesta grande coorte de pacientes com WPW submetidos \u00e0 abla\u00e7\u00e3o de VA, a localiza\u00e7\u00e3o lateral esquerda da VA e a maior idade estiveram independentemente associadas a maior preval\u00eancia de FA cl\u00ednica. Em contraste, a localiza\u00e7\u00e3o posterior da VA e o sexo masculino estiveram associados a maior probabilidade de FA induzida no EEF.<\/jats:p>","DOI":"10.36660\/abc.20260001","type":"journal-article","created":{"date-parts":[[2026,7,22]],"date-time":"2026-07-22T16:59:37Z","timestamp":1784739577000},"source":"Crossref","is-referenced-by-count":0,"title":["Associa\u00e7\u00e3o
