An increasing number of patients are implanted with continuous-flow left ventricular assist devices (LVAD) for the treatment of severe congestive heart failure. In parallel with this growing experience has been an increase in knowledge of how these devices alter cardiac physiology and the important implications this has for cardiac function. Echocardiography offers the ability to provide serial noninvasive evaluation before and after LVAD implantation to document these changes, guide management decisions, and identify LVAD dysfunction. The authors detail a comprehensive assessment of LVAD function by transthoracic echocardiography.
越来越多的患者因严重充血性心力衰竭而植入持续血流左心室辅助装置（LVAD）。随着经验的不断增加，人们对这些设备如何改变心脏生理学以及对心脏功能的重要影响有了更多的了解。超声心动图具有提供 LVAD 植入前后连续非侵入性评估的能力，以记录这些变化，指导管理决策，并识别 LVAD 功能障碍。作者详细介绍了经胸超声心动图对 LVAD 功能的全面评估。
