Abstract

Brugada syndrome (BrS) is a sudden cardiac death syndrome characterized by a coved-type electrocardiogram (ECG). Different disorders, such as ischemia, can emulate a Brugada-pattern ECG (Brugada phenocopy). We report herein, the first case of surgical epicardial electrophysiological mapping in a successfully resuscitated patient with an anomalous aortic origin of the coronary artery (AAOCA) associated with a coved-type ECG. It was debatable whether the coved-type ECG and the abnormal arrhythmogenic substrate in the epicardial right ventricular outflow tract were derived from BrS or from repetitive ischemia due to AAOCA; however, the epicardial electrophysiological mapping helped in deciding the treatment strategy.

Keywords: Brugada phenocopy; Brugada syndrome; ablation; anomalous aortic origin of a coronary artery; ventricular fibrillation.
