Heart transplantation remains a limited option in the treatment of patients with end-stage heart failure because of the shortage of donors and the high incidence of heart failure disease in the Canadian population. The current use of mechanical circulatory support systems is directed primarily at patients at imminent risk of death who are temporarily supported as a bridge to cardiac transplantation. Newer left ventricular assist devices, namely, the axial and centrifugal flow pumps, are smarter and more compact devices. Although used as bridge to transplantation, these devices are now seriously considered to become an option in the chronic treatment of patients with severe and unresponsive congestive heart failure.
由于供体短缺以及加拿大人群中心力衰竭疾病的高发病率，心脏移植在终末期心力衰竭患者的治疗中仍然是一种有限的选择。目前机械循环支持系统的使用主要针对有即将死亡风险的患者，这些患者被临时支持作为心脏移植的桥梁。新型左心室辅助装置，即轴流泵和离心式血泵，是更智能、更紧凑的设备。尽管这些装置被用作移植的桥梁，但现在它们被认真考虑成为重度难治性充血性心力衰竭患者慢性治疗的一种选择。
