Introduction:
Ablation of anteroseptal (parahisian) pathways may be difficult using conventional catheters.
Methods And Results:
Two patients (51 and 20 years old) underwent ablation of a parahisian accessory pathway using the magnetic navigation system Niobe (Stereotaxis, Inc.), which consists of two external permanent magnets (0.08 Tesla) that steer a small magnet embedded in the tip of the ablation catheter. A motor drive allows the advancement or retraction of the catheter. From the control room, the ablation was performed using a single radiofrequency current application (fluoroscopy 3.2 and 6.0 minutes, respectively).
Conclusions:
The Niobe magnetic navigation system was successfully used to perform completely remote controlled mapping and ablation of parahisian accessory pathways.
