超声检测在心衰患者同步化治疗中的应用现状和进展

Advances in Echocardiography on Cardiac Resynchronization Therapy in Patients with Heart Failure

心脏同步化治疗(CRT)已经成为严重心力衰竭以及内科难治性心力衰竭患者的一种可选择性的治疗方法,几项较大的研究证明了CRT的有效性。CRT的治疗机制是改善房室同步性、室间同步性和室内同步性,而超声心动图则可通过M型、脉冲多普勒,组织多普勒,三维成像等技术评估心脏的机械同步性,因此,超声心动图有助于适合CRT患者的筛选,指导电极位置的选择,以及在CRT后起搏器参数的优化和患者随访。本文讨论了目前用于CRT的几种常用的超声技术的优缺点。

Cardiac resynchronization therapy （CRT） has became an alternative treatment in patients with severe medically refractory heart failure in recent years. Several large studies have demonstrated the effectiveness of CRT, which can improve the atrioventricular, interventricular, and intraventricular dyssynchronies. Echocardiography can be used to evaluate cardiac mechanical synchrony by means of M-mode, pulse Doppler, tissue Doppler, 3D, and other techniques, and can therefore be used to screen patients, select lead location, optimize pacemaker parameters, and follow up patients who have undergone CRT. This article reviews the strength and shortcomings of some commonly used echocardiographic techniques when they are applied in patients with heart failure.
