Remaining longevity and evidence of failure of cardiac implantable electrophysiology devices recovered from funeral homes

Background Given the prohibitive cost of pacemakers and defibrillators for medically underserved patients in low‐income countries, these devices are sometimes recovered from funeral homes for charitable reimplantation. Many devices are implanted near the end of the patients’ lives, meaning that recovered devices from funeral homes have the potential for significant remaining longevity. Methods After sending letters asking funeral directors in the Philadelphia area to donate explanted pacemakers and defibrillators, 78 devices were recovered. Sixty‐seven of these devices were successfully interrogated, and 64 devices reported estimates of remaining battery life in years. Twenty‐one defibrillators were also interrogated for evidence of failure. Results Twenty‐two percent of the 64 devices had greater than 4 years of longevity. Fourteen percent of the devices had between 1 and 4 years of longevity, and the remaining 64% had less than 1 year of remaining battery life. We found no evidence from 21 recovered defibrillators that the patient's cause of death was because of defibrillator failure. In almost half (10/21) of the defibrillators, however, the arrhythmia logs were nondecipherable given the entire log was replaced by episodes of signal noise likely occurring after death. Conclusions A significant percentage of devices explanted in funeral homes have suitable remaining battery life for reuse. While no evidence of defibrillator device failure could be found, the analysis was limited by postmortem signal artifact, which may preclude accurate assessment of rates of failure in devices explanted postmortem.
