N\u00e3o existe uma abordagem padronizada para minimizar seus riscos e mortalidade.  Objetivos  Apresentar a experi\u00eancia de sete anos de um monitoramento endosc\u00f3pico sistem\u00e1tico de les\u00e3o esof\u00e1gica ap\u00f3s a abla\u00e7\u00e3o de FA por cateter.  M\u00e9todos  Estudo unic\u00eantrico retrospectivo de avalia\u00e7\u00e3o endosc\u00f3pica sistem\u00e1tica ap\u00f3s abla\u00e7\u00e3o e FA em procedimentos consecutivos realizados entre 2016 e 2022. Um valor de p &lt; 0.05 foi considerado estatisticamente significativo.  Resultados  Foram analisados 823 procedimentos de abla\u00e7\u00e3o de FA com Esofagogastroduodenoscopia (EGD) de controle. A maioria (n=588; 71,4%) dos pacientes submetidos ao procedimento era do sexo masculino, 575 (69,9%) apresentaram FA parox\u00edstica. Monitoramento da temperatura esof\u00e1gica foi realizada usando um sensor \u00fanico em 310 pacientes (40,3%) e uma sonda multissensor em 306 (39,8%) pacientes. As les\u00f5es estavam presentes em 217 EGD (26,5%): hematoma-equimose em 27 (3,3%), eritema em 14 (1,7%), eros\u00e3o em 78 (9,5%) e \u00falcera em 67 (8,2%) pacientes. Nenhuma estrat\u00e9gia de prote\u00e7\u00e3o do es\u00f4fago foi associada \u00e0 maior ocorr\u00eancia de \u00falceras, com exce\u00e7\u00e3o do uso de cateter de ponta de 8mm (14,7% de \u00falceras com cateter de ponta de 8mm vs. 6,7% com outros cateteres, p = 0,001). Les\u00f5es t\u00e9rmicas foram detectadas precocemente e tratadas. A maioria das les\u00f5es foi considerada curada na endoscopia, mas um paciente que foi submetido ao isolamento da veia pulmonar com um cateter de ponta de 8mm apresentou f\u00edstula esof\u00e1gica, que foi tratada com sucesso com clipe met\u00e1lico endosc\u00f3pico e t\u00e9cnica endoloop.  Conclus\u00e3o  A incid\u00eancia de les\u00f5es esof\u00e1gicas \u00e9 alta na EGD de rotina realizada ap\u00f3s a abla\u00e7\u00e3o de FA, embora, na maioria dos casos, sua cura ocorra espontaneamente. Pacientes que se submeteram \u00e0 abla\u00e7\u00e3o com o cateter de ponta de 8mm apresentaram les\u00f5es t\u00e9rmicas mais graves. Endoscopia esof\u00e1gica precoce pode ajudar no diagn\u00f3stico de les\u00f5es em fases iniciais e a preven\u00e7\u00e3o de f\u00edstulas ap\u00f3s a abla\u00e7\u00e3o de FA.<\/jats:p>","DOI":"10.36660\/abc.20230913","type":"journal-article","created":{"date-parts":[[2025,3,25]],"date-time":"2025-03-25T12:15:54Z","timestamp":1742904954000},"source":"Crossref","is-referenced-by-count":0,"title":["Estrat\u00e9gias
