Abstract
Advances in electroanatomic mapping (EAM) technology have facilitated improved success and safety profiles in the field of catheter ablation. However, these advances in their current iteration may be of limited value in ablation performed in very small children. The present case report highlights the application of current EAM technologies in an infant with incessant arrhythmias and includes a discussion regarding the application and limitations of newer mapping and ablation technologies in this unique and fragile patient group.
