超声心动图作为一种无创检查手段可明确诊断主动脉瓣反流,根据反流束的起源、宽度、面积等,运用M型、二维、多普勒、三维和造影等超声技术的多种定性或定量方法评估其反流程度,在判断患者病情、估计预后及选择治疗方式和时机方面具有重要作用。本文对各种超声心动图技术及参数评判AR程度的优、缺点及其适用范围作一综述。
Echocardiography as a non-invasive examination can clearly diagnose aortic regurgitation, according to the origin, width, area, etc. of the back-flow, the use of M-type, two-dimensional, Doppler, three- Qualitative or quantitative methods to assess the degree of reflux, in determining the patient’s condition, prognosis and the choice of treatment and timing plays an important role.
