Area of Science:

  • Cardiology
  • Medical Devices
  • Electrophysiology

Context:

  • Implantable Cardioverter-defibrillators (ICD) are established treatments for ventricular tachyarrhythmias.
  • Technological advancements enable ICD use in a broader patient population.
  • Both primary and secondary prevention trials show ICDs reduce mortality compared to antiarrhythmic drugs.

Purpose:

  • To review the current status and efficacy of ICD therapy for ventricular tachyarrhythmias.
  • To highlight the benefits of ICDs in improving patient survival.
  • To identify unresolved challenges in ICD therapy.

Summary:

  • ICDs are effective for life-threatening ventricular tachyarrhythmias.
  • Device miniaturization and enhanced features expand indications.
  • ICDs demonstrate superior mortality benefits over antiarrhythmic drugs in prevention trials.

Impact:

  • ICD therapy is increasingly recommended for ventricular arrhythmias.
  • Further research is needed to address the limitation of preventing VT/VF recurrence.
  • Optimizing ICD therapy can improve long-term patient outcomes.
