Early Response after Catheter Ablation of the Epicardial Substrate in a Patient with Brugada Syndrome Can Be Predicted by High Precordial Leads

<div>(a) Epicardial mapping revealed an extensive area of low voltage with fragmented and late potential in the anterior RVOT. Gray color of 3D mapping indicates scar tissue, and these areas were measured at 34.4 mm<sup>2</sup>, with the longest total duration of abnormal fractionated potential up to 468 ms and up to 326 ms after the end of the surface QRS. (b) Epicardial ablation was performed targeting the area of low voltage with fragmented and late potential in the anterior epicardial RVOT. (c) Remapped epicardial voltage mapping revealed that these areas were substituted with a scar. RVOT = right ventricular outflow tract.</div>
