With the rising prevalence of heart disease in the United States, there is increasing reliance on durable mechanical circulatory support (MCS) to treat patients with end-stage heart failure. Left ventricular assist devices (LVADs), the most common form of durable MCS, are implanted mechanical pumps that connect to an external power source through a transcutaneous driveline. First-generation LVADs were bulky, pulsatile pumps that were frequently complicated by infection. Second-generation LVADs have an improved design, though infection remains a common and serious complication due to the inherent nature of implanted MCS. Infections can affect any component of the LVAD, with driveline infections being the most common. LVAD infections carry significant morbidity and mortality for LVAD patients. Therefore, it is paramount for the multidisciplinary team of clinicians caring for these patients to be familiar with this complication. We review the epidemiology, prevention, diagnosis, treatment, and outcomes of LVAD infections.
随着美国心脏病患病率的上升,人们越来越依赖耐用的机械循环支持(MCS)来治疗终末期心力衰竭患者。左心室辅助装置(LVAD)是最常见的耐用MCS形式,是通过经皮驱动线连接到外部电源的植入式机械泵。第一代LVAD体积庞大,是搏动性泵,常因感染而出现并发症。第二代LVAD设计有所改进,但由于植入式MCS的固有特性,感染仍然是常见且严重的并发症。感染可影响LVAD的任何部件,其中驱动线感染最为常见。LVAD感染给LVAD患者带来了显著的发病率和死亡率。因此,照顾这些患者的多学科临床医生团队熟悉这种并发症至关重要。我们综述了LVAD感染的流行病学、预防、诊断、治疗及预后。
