Background: Implantable Cardioverter Defi brillator (ICD) is the most important management for prevention of Sudden Cardiac Death (SCD) in patients with arrhythmogenic right ventricular cardiomyopathy (ARVC). However, some patients may receive multiple ICD therapies in a short period, a condition referred as electrical storm (ES). Objectives: Th is study aimed to determine the prevalence, therapeutic options, and prognostic implications of ES in ARVC patients with an ICD. Methods: We retrospectively analyzed the baseline and follow-up data of 39 ARVC patients with an ICD. ES was defi ned as three or more separated episodes of Ventricular Tachycardia or Ventricular Fibrillation (VT/VF) within a 24 hour period. Results: During a median follow-up of 49 months (range 6-225), 12 of 39 (31%) patients suff ered at least one episode of ES. Th e interval between the fi rst ES and the initial ICD implantation ranged from 1 month to 109 months, and ES was the fi rst ICD discharge in three patients. Th e median number of VT/VF events per ES was four (range 3��?39). Five patients experienced 20 episodes of ES that were treated by antitachycardia pacing only, while the other seven patients suff ered shock therapies during ES. In three patients, ES required emergency hospitalization and the repeatedly occurred VT/VF was fi nally subsided by intravenous amiodarone. Th ere was no signifi cant diff erence in actual survival between patients with and without such an event. Conclusions: ES is not rare in ARVC patients with an ICD for prevention of SCD, but it does not independently confer increased mortality. Intravenous amiodarone is eff ective in management of ES when VT/VF repeatedly occurred. Recent Publications: 1.
