Does remote catheter ablation using a magnetic navigation system allow successful ablation of parahisian accessory pathways?
The Niobe magnetic navigation system can be successfully used for remote controlled mapping and ablation of parahisian accessory pathways.
Answers are grounded in this paper and cite their sources.
Remote magnetic navigation shows initial feasibility for parahisian ablation; hypothesis-generating and requires larger trials before adoption.
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.
