摘　　要：主动脉瓣反流(aortic regurgitation, AR)是左心室辅助装置(left ventricular assist device, LVAD)置入术后的常见并发症, 导致临床预后不良。超声心动图是评估主动脉瓣(aortic valve, AV)功能的主要手段, 本文重点概括超声心动图用于LVAD术前和术后AR定量评估的指标参数, 同时结合目前的AR处理方法, 在现有临床证据条件下对LAVD全程管理中AR的预防和处理策略做出全面总结。Aortic regurgitation(AR)is a common complication after left ventricular assist device(LVAD)implantation,leading to poor clinical prognosis.Echocardiography is the main method for evaluating the function of the aortic valve(AV).This article focuses on summarizing the indicators and parameters of echocardiography used in the quantitative evaluation of AR before and after LVAD,combined with the current AR management methods.Based on the existing clinical evidence,the prevention and treatment strategies of AR in the whole-process management of LAVD were summarized.
