| 心脏瓣膜病(valvular heart disease, VHD)由于心腔内血流动力学异常,可导致心功能减低及心肌受损,决定瓣膜病患者的手术收益与风险,因此瓣膜病患者术前心功能的评估十分重要。应用超声技术在明确诊断心脏瓣膜病变的同时,准确评估心功能及心肌受损程度,选择恰当的治疗时机和治疗方案,对患者预后和生存质量的改善极其重要。近年来随着超声技术的发展,涌现出的新技术能够为心脏运动功能获得相对更为准确的定量诊断数据,尤其是斑点追踪技术的应用,为早期诊断瓣膜病患者心肌受损及手术风险分层具有临床应用价值。本文就超声新技术评价心脏瓣膜病患者心功能与心肌受损的研究进展进行综述。 |

| Abstract: |
| ABSTRACT Valvular heart disease（心脏瓣膜病）can cause chronic cardiac dysfunction and impaired myocardium due to the abnormalities of intracardiac hemodynamics，therefore it is important to evaluate the cardiac function of patients with 心脏瓣膜病 before cardiac surgery for the determination of surgical benefit and risk. With clear diagnosis of the diseased valve by echocardiography，the accurate assessment of cardiac function and impaired myocardial motion would be also crucial for the selection and timing of cardiac surgery.With the development of ultrasonic technology，emerging novel techniques of echocardiography can obtain data for accurate and quantitative diagnosis by the evaluation of cardiac mechanics，especially speckle tracking echocardiography，which has clinical value for early diagnosis of impaired myocardium and surgical risk stratification of 心脏瓣膜病. In this article，we reviewed the research progress of novel echocardiography techniques on the evaluation of cardiac function and impaired myocardium in 心脏瓣膜病 patients. |
