Echo Doppler makes a fundamental contribution to the non-invasive quantification of mitral valve disease. It enables calculation of gradients and of orifice surface area in mitral stenosis. The quantification of mitral insufficiency is also possible though more difficult: it is based upon the combination of semi-quantitative and quantitative methods, in particular the calculation of regurgitation fraction obtained by comparison of flow rates at different orifices in cases of pure regurgitation. Finally, the calculation of pulmonary artery pressures from a Doppler record in tricuspid and pulmonary insufficiency can be used to assess the effects of mitral valve disease on the pulmonary circulation. Echo Doppler thus provides a reliable non-invasive hemodynamic assessment of mitral valve disease and should lead to a reduction in the number of invasive investigations in this type of valve disease.
超声多普勒对二尖瓣疾病的无创定量评估做出了重要贡献。它能够计算二尖瓣狭窄时的压力阶差和瓣口面积。二尖瓣反流的定量评估虽然更具难度但也是可行的：它基于半定量和定量方法的结合，特别是在单纯反流情况下，通过比较不同瓣口的流速来计算反流分数。最后，利用三尖瓣和肺动脉反流的多普勒记录计算肺动脉压力，可用于评估二尖瓣疾病对肺循环的影响。因此，超声多普勒为二尖瓣疾病提供了可靠的无创血流动力学评估，应该能够减少这类瓣膜疾病的侵入性检查数量。
