There was a strong preference to donate explanted devices for reuse in humans (61.9%). The group of age younger than average was more against storing explanted CIEDs (p= 0.014). 57.1% considered it would be beneficial for patients to have a document so they could reflect their wishes regarding device handling after their death. 88.1% indicated that they would strongly agree or to implant postmortem resterilized pacemakers or ICDs (Implantable cardioverter defibrillator) containing >70% of the original battery life in patients who were unable to obtain a new one, the older than average age group was showed more agreement with this statement (p=0.02). The most mentioned concerns were device malfunction (57.1%) and infection (54.8%). d) Conclusions The majority of respondents support reusable CIEDs donation to developing countries. It would be interesting to study the feasibility of a nationwide CIED reutilization programme.
