Quando indicar ablação para as principaisarritmias atriais e ventriculares

Arritmias supraventriculares sao disturbios do ritmo comuns na pratica clinica diaria. As duas principais opcoes de tratamento sao o medicamentoso, considerado de segunda linha devido a baixa eficacia, necessidade de uso por longa data, efeitos colaterais, interacaomedicamentosa e potencial efeito proarritmico; e o invasivo com ablacao, atualmente o padrao ouro devido a baixa complicacao e alta eficacia. As arritmias ventriculares sao menos comuns, podendo estar associadas a prognostico e risco de morte subita cardiacadiferentes, de acordo com a presenca ou nao de alteracao estrutural cardiaca. A ablacao por cateter possui papel diferente no tratamento das arritmias ventriculares nestes dois grupos de pacientes. O objetivo desta revisao e avaliar o papel da ablacao por cateter,resumindo as principais indicacoes deste procedimento no manuseio das arritmias supraventriculares e ventriculares... Supraventricular arrhythmias are common rhythm disturbances in daily clinical practice. The two main treatment options are pharmacological, and catheter ablation. Pharmacologicaltreatment is considered the second line option due to its low efficacy, the need for long-term adherence, the risk of side effects, drug interactions, and potential proarrhythmic effects. Catheter ablation is currently the gold standard therapy, due to its low complications and high efficacy. Ventricular arrhythmias are less common, and may be associated with different prognoses and levels of risk of sudden cardiac death, depending on the presence or absence of structural heart disease. Catheter ablation has a different role in the treatment of ventricular arrhythmias in these two groups of patients. The objective ofthis review is to evaluate the role of catheter ablation, summarizing the main indications of this procedure in the management of supraventricular and ventricular arrhythmia...
