Possible arrhythmic recurrences and the risk of sudden cardiac death (SCD) in this setting are reasons for concern, and limited data have been published to guide clinical management of these patients. The pooled proportion of patients who experienced VA recurrence was 0.41 (95% CI 0.30 to 0.53, p=0.13).

For the past four decades, implantable cardioverter defibrillator (ICD) therapy has become the standard of care for preventing sudden cardiac death in high-risk individuals. The rate of ICD implantation has risen due to the increasing population age and the growing prevalence of cardiac arrhythmias.
