Empiric Slow Pathway Ablation vs. no Ablation in Patients With Non‐Inducible Supraventricular Tachycardia

The mean age was 50.2 ± 16 years, and 62% were female. During a mean follow-up of 3.8 years, recurrence rates were similar (15% vs. 26.7%, p = 0.28)., but no patients in empiric ablation group had AVNRT whereas 53% of non-ablation patients had AVNRT. All the early recurrences were due to AVNRT while the late recurrences were predominantly due to non AVNRT arrhythmias. Time to recurrence was longer in the ablation group (54 vs. 9.8 months). There were no AV blocks after empiric ablation CONCLUSION: In patients with DAVNP and non-inducible tachycardia, overall recurrence rates are similar regardless of empiric ablation, however it is efficacious is preventing early arrhythmia recurrence and true AVNRT recurrences.
