Permanent Pacemaker and Implantable Cardioverter Defibrillator Infection

Abstract
The estimated rate of cardiac device infection after permanent endocardial pacemaker (PPM) or implantable cardioverter-defibrillator (hereafter, defibrillator) implantation has varied from 0.13% to 19.9%1,2 but has increased by 124% over the past decade.3 Prior studies, however, have been limited by lack of person-time data, and these rates are difficult to interpret. Results from treatment with prolonged parenteral antibiotics in the absence of hardware removal have thus far been disappointing.4-9 Therefore, the prevailing opinion is to remove the complete device system if infection is confirmed.10,11 Accurate diagnosis of device infection is essential to ensure that patients with infection are treated appropriately, including device removal if indicated. A correct diagnosis is equally important among patients who do not have device infection so that unnecessary device removal does not occur because many patients are device dependent, and life-threatening complications of device removal can occur.4,12,13
