本文提炼自《美国心脏病学会杂志》(J Am CollCardiol)的一篇综述类文章,主要介绍了作为心脏移植替代方式的左心室辅助装置应用前景,下面为该综述的十大要点:

 1.由于心脏供体持续短缺而终末期心衰患者数量越来越多,左室辅助装置(LVAD)是心脏移植患者的桥接治疗方式,也是患者不适合心脏移植时的替代治疗方法。

 2.虽然不断有新的方式增加捐赠器官来源,但器官可获得性依然是心脏移植的主要限制条件。

 3.对于射血分数降低的难治性终末期(HFrEF)患者,现行的主要治疗策略是初始筛选确定适合心脏移植的患者,然后考虑给予不适合心脏移植的患者次级处理,即作为替代治疗的心室辅助装置(VAD)。

 4.终末期心衰治疗的现行筛选方法需要修改,新的筛选办法应转变思维方式,在初始治疗即考虑VAD替代治疗,而将心脏移植留给特定人群,或将心脏移植作为一种救助性治疗(bailout therapy)。

 5.与药物治疗相比,VAD进一步改善了患者生存率及生存质量,在某些病例,VAD的2年预后甚至可以与心脏移植媲美。近些年来,LVAD的每年手术量大于心脏移植。

 6. LVAD存在一定的并发症,这或消减学界在轻微病情患者群体的LVAD研究热情。但技术进步会解决并发症问题。

 7.设备小型化、移植整体化、搏动同步化及监控远程化是LVAD技术进步的方向,这将扩大VAD的适用范围。

 8. LVAD在何类患者能够带来比心脏移植更多的治疗收益,这个问题需要临床试验解答。

 9.由于LVAD技术发展迅速,因此,LVAD比心脏移植有着更高的可获得性。

 10.未来治疗策略很可能是:LVAD作为终末期心室的初始治疗方式,而心脏移植作为特定患者或VAD治疗失败后的治疗方式。
