[Pacemaker infection in fragile patients].

Complications associated with cardiac implantable electric devices (CIED) are manifold. They include lead dislocation, twiddler's syndrome, device malfunction, haematoma formation and infection. Infections can be divided into acute, subacute and late infections. Both the time of onset and the route of infection play a crucial role. The consequences of a CIED infection are devastating. The most modern treatment methods include the removal of all implanted implants. If complete removal is not followed in the event of infection, there is a high rate of infection recurrence. Open thoracic surgery to remove infected CIED hardware has been replaced by percutaneous lead extraction procedures. Lead extraction requires specialised equipment and expertise and may not be readily available or feasible for some patients. Each extraction procedure is associated with a small risk of potentially fatal complications (e.g. cardiac avulsion, vascular avulsion, haemothorax and cardiac tamponade). For these reasons, the performance of such procedures should be limited to centres with adequate equipment and experience. Successful salvage of CIED systems with in situ sterilisation of contaminated hardware has been reported. In our case, we report the successful salvage of an exposed generator in a frail patient treated more than 5 years after the last generator replacement.
