  • Title: [Study of flow field uniformity downstream of mitral stenosis using Doppler echocardiography].
    Author: Shi Y, Zhang G, Tang L.
    Journal: Hua Xi Yi Ke Da Xue Xue Bao; 1998 Jun; 29(2):136-9. PubMed ID: 10684000.
    Abstract:
    To research into the relationship between mitral lesion, stenosed degree and flow field uniformity downstream of mitral valve, we adopted the advanced color Doppler echocardiographic technique to conduct a quantitative study of flow field uniformity downstream of mitral valve in sixty patients with varying-degree of mitral stenosis in vivo. Twenty normal persons acted for comparison. The results showed that there was a linear correlation between the extent of valvular lesion, the stenosed degree and flow field uniformity downstream of mitral valve. We conclude that the more severe the mitral lesion is, the more grave the stenosis is and the worse the flow field uniformity is. This suggests that there might be a reciprocity between valvular lesion and flow field uniformity as well as turbulent shear stress, which should be further studied.
