[In Germany too many ICD implantations are performed: pro]

Implantable cardioverter defibrillators (ICD) have undoubtedly developed into one of the most successful therapies in the field of cardiology over the last decades; however, a significant number of ICD operations are carried out in patients who do not benefit from ICD therapy despite significant left ventricular dysfunction. These patients can easily be identified. An ICD therapy does not prolong life in the setting of significant chronic kidney disease. In elderly patients the benefit of prophylactic ICD therapy is very small. Simple risk scores can identify other patients who do not benefit from this treatment. The number of ICD operations can also be significantly reduced by the use of devices with an extended longevity.
