Pupose To study the influence of left atrial diameter, area of mitral orifice and mitral regurgitation on thrombosis in left atrium.

Methods RT-3DCE and 2de were applied on 10 patients with EMR and got regurgitation volume, left atrial volume and their ratio to evaluate the degree of EMR.

方法应用实时三维彩色超声心动图和二维超声心动图(2de)测量10例二尖瓣偏心反流患者的二尖瓣偏心反流容积、左心房容积及二者比值，评价二尖瓣偏心反流的程度。

Conclusion: Doppler echocardiography provides a reliable and accurate method for complete non-invasive assessment of left atrial pressure in patients with mitral regurgitation.

结论：多普勒超声为无创性测定左房压提供一种可靠而准确的新途径。

The motion cites a sworn statement by echocardiogram technician Marti McCulloch that Fleming instructed her to use an incorrect technique for measuring atrial regurgitation, a key component of fen-phen claims.
