Remote magnetic catheter mapping and ablation of permanent junctional reciprocating tachycardia in a seven-year-old child.
BACKGROUND
Mapping and catheter ablation of permanent junctional reciprocating tachycardia (PJRT) in children can be challenging. Remote magnetic navigation may improve precise mapping and catheter stability during ablation, as well as reduce fluoroscopy time, especially in conjunction with a non-fluoroscopic mapping system.


OBJECTIVE
We report a case of PJRT ablation in a 7-year-old child using remote magnetic navigation.


RESULTS
Mapping of the right atrium (RA) and the coronary sinus (CS) and catheter ablation were performed using remote magnetic navigation in conjunction with a non-fluoroscopic mapping system (NavX). We observed excellent catheter steering abilities and constant wall contact during ablation, allowing a short and safe procedure.


CONCLUSIONS
Remote magnetic navigation may be used for mapping and ablation of PJRT in children.
