The authors discuss principles of continuous flow left ventricular assist device (LVAD) operation, basic differences between the axial and centrifugal flow designs and hemodynamic performance, normal LVAD physiology, and device interaction with the heart. Systematic interpretation of LVAD parameters and recognition of abnormal patterns of flow and pulsatility on the device interrogation are necessary for clinical assessment of the patient. Optimization of pump flow using LVAD parameters and echocardiographic and hemodynamics guidance are reviewed.
作者讨论了连续血流左心室辅助装置（LVAD）的操作原则、轴向和离心流设计以及血液动力学性能的基本差异、正常 LVAD 生理学以及装置与心脏的相互作用。对 LVAD 参数的系统解释以及对设备检测中异常血流和脉动模式的识别是对患者进行临床评估的必要条件。本文回顾了使用 LVAD 参数以及超声心动图和血液动力学指导来优化泵流量。
