To better understand the forensic implications of death with a left ventricular assist device (LVAD), we reviewed all deaths that were reported to a regional medical examiner jurisdiction involving patients who had an LVAD.
Medical examiner case files between January 2012 and September 2018 were searched for "LVAD" and "left ventricular assist device" to identify deaths that were reported to the medical examiner involving a decedent who had an LVAD at the time of death.
During the study period, a total of 14 deaths were reported to the regional medical examiner involving decedents who had an implanted LVAD at the time of death. The average age at death was 64 years, with a range from 40 to 81 years. The underlying cardiac disease leading to LVAD implantation was ischemic heart disease (n = 9), nonischemic dilated cardiomyopathy (n = 4), and chemotherapy-related cardiotoxicity (n = 1). Of these 14 deaths, 2 deaths were due to loss of power to the LVAD, 1 death was due to traumatic subdural hemorrhage occurring in the setting of anticoagulation therapy required by LVAD implantation, and 1 death was due to femur fracture following a fall.
Medical examiners should be familiar with the potential complications of LVADs, especially those complications that may prompt consideration of non-natural manners of death. Medical examiners should also be aware of the tools and investigative strategies that may assist in the investigation of LVAD-related deaths.
为了更好地理解左心室辅助装置(LVAD)相关死亡的法医学意义,我们回顾了向地区法医管辖机构报告的所有涉及使用LVAD患者的死亡案例。
检索2012年1月至2018年9月期间法医的案件档案,查找“LVAD”和“左心室辅助装置”,以确定向法医报告的涉及在死亡时使用LVAD的死者的死亡案例。
在研究期间,地区法医共报告了14例死亡案例,死者在死亡时植入了LVAD。平均死亡年龄为64岁,范围为40至81岁。导致植入LVAD的潜在心脏疾病为缺血性心脏病(n = 9)、非缺血性扩张型心肌病(n = 4)和化疗相关心脏毒性(n = 1)。在这14例死亡中,2例是由于LVAD断电,1例是由于在LVAD植入所需的抗凝治疗过程中发生创伤性硬膜下出血,1例是由于跌倒后股骨骨折。
法医应熟悉LVAD的潜在并发症,尤其是那些可能促使考虑非自然死亡方式的并发症。法医还应了解可能有助于调查LVAD相关死亡的工具和调查策略。
