A NavXTM-guided ablation of a nodo-fascicular fibre
Medizinische Klinik I, Klinikum Grosshadern, Universität München, Marchioninstr. 15, Munich, Germany
The NavXTM system was used to guide mapping and successful ablation of a reciprocating antidromic tachycardia involving anterograde conduction over a nodo-fascicular fibre and retrograde conduction over the His bundle and AV node. This novel mapping system allowed visualization of the lower insertion site of the nodo-fascicular accessory pathway
1.52 cm away from the tricuspid annulus in a three-dimensional reconstruction of the right atrium and right ventricle.
Key Words: Accessory pathway, Arrhythmia, Three-dimensional, Catheter ablation
