Delayed infection of the automatic implantable cardioverter-defibrillator. Current recognition and management

Three cases of delayed infection of automatic implantable cardioverter-defibrillator devices without systemic manifestations are reported. Computed tomographic scan of the heart revealed fluid deep to the patch in each case. Sonication of explanted automatic implantable cardioverter-defibrillator patches facilitated the recovery of adherent microorganisms in one case. Management of this previously unrecognized problem is outlined.
