The incidence of electric storm (ES) is increasing with the use of implantable cardioverter defibrillators (ICDs) in a wider range of indications. ES can develop in both ischemic and non-ischemic heart diseases, significantly increasing short and long-term mortality. It is a life-threatening condition, and the treatment can be challenging even for experienced doctors as well. In the antiarrhythmic drug refractory cases, catheter ablation (CA) can be an effective solution. Although much of the available data comes from non-randomized small studies, it appears that CA can reduce the recurrences of arrhythmias and improve survival. The aim of our paper is to investigate the role of CA in the therapy in ES, and to demonstrate possible alternative therapeutic options.
