Sasaki et al. for the first time provide systematic analysis of the recorded electrograms in the aortic cusps.9 In doing so, they help provide an electrical navigation adjunct to fluoroscopy and intracardiac echocardiography to help guide and determine mapping catheter location in this complex anatomic region. Further study to determine precisely what the actual source of these electrograms and thus the nature of the arrhythmogenic substrate mapped and targeted for ablation is needed.
