Mechanical circulatory support with continuous-flow left ventricular assist devices (LVADs) has emerged as a viable treatment modality for patients with advanced heart failure. LVAD support results in unique haemodynamic and echocardiographic alterations that must be understood to provide optimal care for these patients. In this review, we propose essential echocardiographic and haemodynamic elements for the assessment of optimal LVAD function based on the literature and the use of simulation software. A key element of LVAD physiology remains the interaction between an unloaded left ventricle and a loaded right ventricle. The echocardiographic assessment and treatment of the pathophysiology of the right-sided part of the heart remains critical to maintaining optimal LVAD support.
机械循环支持与左心室辅助装置（LVAD）的连续血流已成为治疗晚期心力衰竭患者的可行方法。LVAD 支持会导致独特的血液动力学和超声心动图改变，必须加以理解，才能为这些患者提供最佳护理。在这篇综述中，我们根据文献和模拟软件的使用，提出了评估 LVAD 功能的基本超声心动图和血液动力学要素。LVAD 生理学的一个关键要素仍然是空载的左心室和负载的右心室之间的相互作用。对右心病理生理学的超声心动图评估和治疗仍然是维持最佳 LVAD 支持的关键。
