Epicardial Ablation in Brugada Syndrome

Card Electrophysiol Clin. 2020 Sep;12(3):345-356. doi: 10.1016/j.ccep.2020.04.006. Epub 2020 Jun 27.


Brugada syndrome is an inherited cardiac condition characterized by a typical electrocardiogram signature of coved-type ST-segment elevation in the right precordial leads and ventricular arrhythmias leading to sudden cardiac death, in the absence of unequivocal structural heart disease. Brugada syndrome specifically affects the right ventricle, which predisposes to cardiac arrest. Besides medical management with quinidine, emerging data indicate that catheter ablation can help reduce the ventricular arrhythmia burden in these patients. This review explores the mechanisms of ventricular arrhythmia, current approaches and evidence for ablating the epicardial arrhythmogenic substrate in this condition.
