The continuous-flow left ventricular assist device (CF-LVAD) is used to save the lives of patients in the final stage of congestive heart failure, replacing the pump function of the left ventricle. Although quality of life increases significantly, CF-LVAD-related complications might prove fatal, as in the case presented in this paper. A 20-year-old female, during her second pregnancy, presented with signs of heart failure. Emergency caesarean section was necessary to save the baby, but peripartum cardiomyopathy developed in the mother. The use of an implantable cardioverter-defibrillator (ICD) was necessary 5 years later. As the clinical progression was unfavorable under medical treatment, with the patient reaching INTERMACS (Interagency Registry for Mechanically Assisted Circulatory Support) Profile 1 (refractory cardiogenic shock), the treatment of choice was the implantation of a CF-LVAD. After 3 years of follow-up (at the age of 28), the patient presented with a positive hemoculture for . Prolonged antibiotic therapy and attentive follow-up was prescribed. Although an effective antiplatelet and anticoagulant treatment was applied, and despite therapeutic values of prothrombin time and international normalized ratio (INR), the patient died as result of a fatal cerebral hemorrhage. The autopsy also revealed septic emboli, disseminated intravascular coagulation, and focal proliferative glomerulonephritis. Although the benefits of CF-LVAD are significant, bleeding episodes can be severe and LVAD-associated infection can trigger glomerular injury and increase mortality.
持续流左心室辅助装置(CF-LVAD)用于挽救充血性心力衰竭末期患者的生命,替代左心室的泵功能。尽管生活质量显著提高,但 CF-LVAD 相关并发症可能致命,正如本文所介绍的病例。一名 20 岁女性在第二次妊娠时出现心力衰竭迹象。为了挽救婴儿,必须进行紧急剖腹产,但母亲出现围产期心肌病。5 年后需要使用植入式心脏复律除颤器(ICD)。由于在药物治疗下临床进展不利,患者达到 INTERMACS(机械循环辅助支持机构间注册)1 级(难治性心源性休克),因此首选治疗方法是植入 CF-LVAD。随访 3 年后(28 岁),患者血液培养呈阳性。开出了延长抗生素治疗和密切随访的医嘱。尽管应用了有效的抗血小板和抗凝治疗,并且凝血酶原时间和国际标准化比值(INR)的治疗值正常,但患者仍因致命性脑出血而死亡。尸检还显示感染性栓子、弥散性血管内凝血和局灶性增生性肾小球肾炎。虽然 CF-LVAD 的益处显著,但出血事件可能严重,LVAD 相关感染可引发肾小球损伤并增加死亡率。
