Empiric Ablation Slow Pathway Modification
Question:
Can I bill for an empric ablation of slow pathway?
Ventricular pacing - VA conduction was present as baselinem midline, and decremetnal. Ventricular extrastimulus testing was performed with retograde AVNERP=500/300/290ms and VERP 500/240ms.
Atrial pacing - incremetnal atrial pacing show no pre-excitation. AV Wenchebach cycle length=410ms. With atrial extrastimuli dual AV notal physiology was persent, AVNERP=500/370ms. Patient started on Isuprel. With pacing Typical AVNRT could be induced but double echos were easily reproduced. Patient was not inducible for Atrial tachycardia or Atrial Fibrillation. Decision was made to perform empiric slow pathway modification.
Ablation: Slow pathway modification was performed by RF ablation.
Post Ablation: AH & HV intervals were unchanged. With isuprel and atrial pacing, AVNERP=500/350ms. AV nodal echos could not be induced.
Conclusion:
Dual AV nodal physiology was persent and double echos were noted. Patient likely has AVNRT.
Successful ablation for slow pathway for treatment of typical AVNRT.
