Implantable Atrial Defibrillator: Which Results and Indications?

  • W. Jung
  • B. Lüderitz


Atrial fibrillation (AF) is a frequent and costly health care problem and represents the most common arrhythmia resulting in hospital admission. The overall prevalence of AF in the United States ranges from <1% in young, otherwise healthy individuals up to nearly 9% in elderly patients. AF may cause disabling symptoms and serious adverse effects such as impairment of cardiac function or thromboembolic events. Due to the limited efficacy of antiarrhythmic drugs for AF, several non-pharmacologic options have evolved including pacemaker therapy, transvenous catheter ablation techniques, surgical procedures, and treatment with an implantable atrial defibrillator (IAD). The high prevalence of AF and its clinical complications, the poor efficacy of medical therapy for preventing recurrences, and dissatisfaction with alternative modes of therapy stimulated interest in an IAD [1].
