The aim of the study was to analyze the usefulness of RFA in controlling arrhythmic storm due to hemodynamically stable VT in a cohort of patients with an ICD and to evaluate the incidence of arrhythmic storm among patients with an ICD. A group of 13 (3%) of 403 consecutive ICD recipients were submitted to RFA of VT during an arrhythmic storm. Two additional patients were referred from other institutions. Standard criteria were used for VT endocardial ablation. A transcatheter epicardial approach was required in three patients. A total of 18 procedures were performed in 15 patients. A mean of 13.2 ± 9.7 pulses of RF were delivered. Clinical tachycardia was successfully ablated in 12 (80%) patients. One patient died in incessant VT, 1 patient underwent heart transplant, and 1 was treated with direct current ablation. During a mean follow‐up of 12 ± 17 months, only two patients suffered a single episode of VT. Arrhythmic storm requiring VT ablation was uncommon among patients with an ICD and occurred late after ICD implantation. The arrhythmic episode was successfully controlled in the majority of patients with endocardial or epicardial RFA. (PACE 2004; 27:971–975)
