he implantable cardioverter-defibrillator (ICD) is an established treatment for the prevention of sudden cardiac death in patients with a history of lifethreatening ventricular tachyarrhythmias, 1 and recent studies have reported their efficacy in the primary prevention of sudden cardiac death in patients with structural heart disease and decreased left ventricular (LV) function. [2][3][4] Therefore, the number of cases of prophylactic use of ICDs has increased worldwide, and as both the number of patients with an ICD and the follow-up period after implantation have increased, several issues concerning ICD management, including lead fractures, have arisen. 5 ICD lead failures associated with long-term fatigue is a serious complication because it results in oversensing of noise and subsequent inappropriate shocks or failure of the ICD to deliver a shock. In particular, ICD leads with a coaxial polyurethane insulated design have frequently been the cause of lead failures and inappropriate shocks. 6,7 However, the long-term consequences of ICD lead malfunctions in the Japanese patient population have not been analyzed and that was the goal of the present study.
