Does epicardial mapping and ablation normalize the electrocardiogram in an asymptomatic patient with Brugada syndrome?
Epicardial mapping and ablation of abnormal potentials can normalize the electrocardiogram in asymptomatic Brugada syndrome.
May support epicardial ablation for ECG normalization in asymptomatic Brugada; hypothesis-generating and requires prospective validation.
Key Teaching Points•Epicardial mapping was done in a patient with sporadic and entirely asymptomatic Brugada syndrome.•Multiple abnormal potentials were recorded on the right ventricle epicardium, especially from below the pulmonary artery valve to above the tricuspid annulus.•The electrocardiogram was normalized after ablation of the abnormal epicardial potentials. •Epicardial mapping was done in a patient with sporadic and entirely asymptomatic Brugada syndrome.•Multiple abnormal potentials were recorded on the right ventricle epicardium, especially from below the pulmonary artery valve to above the tricuspid annulus.•The electrocardiogram was normalized after ablation of the abnormal epicardial potentials.

Watanabe et al. (2019) conducted a case report in Brugada syndrome (n=1). Epicardial mapping and radiofrequency catheter ablation was evaluated on Normalization of electrocardiogram and elimination of late potentials. Epicardial mapping and radiofrequency ablation of abnormal delayed potentials in the right ventricular outflow tract eliminated the Brugada-type ST elevation and normalized the electrocardiogram in an asymptomatic patient.
