Sudden cardiac death is defined as a natural death due to termination of cardiac activity associated with loss of consciousness, spontaneous breathing and circulation. Nowadays, the prevention of sudden cardiac death represents a major issue and many areas of uncertainty are not met by current evidences. Among those, reliable tools for risk stratification are still lacking, as well as solution for patients in which the risk of sudden cardiac death is due to a transient or correctable condition.The concept of the wearable cardioverter defibrillator is based on a potential solution for such grey areas. It merges long-term monitoring capabilities, shockable rhythm discrimination and shock delivery without the need for bystander assistance or invasive procedures. The present review aims to summarize current problems in dealing with this insidious condition, and to discuss potential options for patients in whom sudden cardiac death could be prevented more safely and cost-effectively.
