Ablation data are currently limited to a small, select population of patients with refractory ventricular fibrillation (VF) storm with medium duration of follow-up. It might be too early to recommend against the implantation of implantable cardioverter-defibrillators in patients with successfully ablated medically refractory index VF storm. Further study is needed to define the role of ablation in cases that are not medically refractory.
