Indication for ICD or WCD?

The implantable cardioverter defibrillator (ICD) represented a breakthrough in the prevention of sudden cardiac death. In addition to its use in secondary prevention, the indication of ICD therapy in primary prevention is also being intensively researched. A study published last year evaluated the relevance of ICD implantation in the acute phase of acute myocarditis and a registry study investigated the benefits of a wearable cardioverter defibrillator (WCD) for the prevention of sudden cardiac death in post-infarction patients.
