CONCLUSION
The novel anatomic ICE-guided catheter ablation approach aimed to identify the earliest activation at the AR with an extension of RF lesions towards its septal region seems effective and safe to modulate the SN in symptomatic patients with IST refractory to medical treatment. This technique is reproducible and minimally invasive when compared to more complex approaches such as epicardial SNM or surgical/ hybrid ablation procedures. This approach however, needs to be tested in a larger cohort of patients.
