Um aumento nas recorr\u00eancias precoces e tardias ap\u00f3s a crioabla\u00e7\u00e3o \u00e9 relatado como uma desvantagem importante.  Objetivos  Neste estudo, objetivamos comparar o sucesso do procedimento agudo e as taxas de recorr\u00eancia em longo prazo de pacientes com TRNAV submetidos a m\u00e9todos.  M\u00e9todos  Foram inclu\u00eddos no estudo 73 pacientes com TRNAV: 32 com crioabla\u00e7\u00e3o e 41 com abla\u00e7\u00e3o por RF. N\u00e3o houve diferen\u00e7a estatisticamente significativa entre o sucesso agudo do procedimento nos m\u00e9todos. O procedimento de abla\u00e7\u00e3o foi realizado por operador com experi\u00eancia em arritmologia. A escolha entre RF ou crioabla\u00e7\u00e3o foi feita no laborat\u00f3rio de eletrofisiologia com base no material j\u00e1 dispon\u00edvel durante o procedimento. Ap\u00f3s o procedimento, os pacientes foram avaliados a cada 3 meses durante 2 anos em controle policl\u00ednico. O n\u00edvel de signific\u00e2ncia adotado na an\u00e1lise estat\u00edstica foi de 5%.  Resultados  Os dois grupos de pacientes foram homog\u00eaneos. O tempo de fluoroscopia (p&lt;0,001) foi menor, mas os tempos his-\u00e1trio (p=0,004) e his-ventricular (p=0,015) foram maiores no grupo crioabla\u00e7\u00e3o. N\u00e3o houve diferen\u00e7a significativa em termos de sucesso agudo do procedimento, salto p\u00f3s-procedimento sem eco \u00fanico e presen\u00e7a de eco e salto.  Conclus\u00f5es  A crioabla\u00e7\u00e3o requer menos tempo de fluoroscopia e \u00e9 uma alternativa segura e n\u00e3o inferior \u00e0 abla\u00e7\u00e3o por RF em pacientes com TRNAV. O risco de bloqueio AV \u00e9 um problema significativo com o uso de energia de RF, tornando-o menos adequado para uso em pacientes jovens e fisicamente ativos.<\/jats:p>","DOI":"10.36660\/abc.20230604","type":"journal-article","created":{"date-parts":[[2024,10,8]],"date-time":"2024-10-08T11:44:52Z","timestamp":1728387892000},"source":"Crossref","is-referenced-by-count":1,"title":["Abla\u00e7\u00e3o
