Abstract

In children, the Impella^® is most commonly used in the setting of cardiogenic shock. There are few reported cases of Impella^® use in pediatric patients undergoing ablation; description of troubleshooting techniques may improve success rates. We describe a pediatric patient with tachycardia-induced cardiomyopathy due to incessant ectopic atrial tachycardia whose ablation was notable for significant electromagnetic interference (EMI) from the Impella^® leading to incomplete mapping. This case highlights the need for multidisciplinary planning and consideration of possible EMI with the use of magnet-based electroanatomic mapping systems as well as troubleshooting techniques to reduce the impact of EMI.
