The cine- and angiocardiographic method permits a quantitative evaluation of the left atrial volume. The maximum volume of the left atrium was found to increase along with the enhancement of mitral regurgitation. Mitral insufficiency is not always accompanied by a "systolic expansion" of the left atrium. The size of the left atrium chamber is mainly determined by the state of the myocardium, and does not much depend on the elevation of the intra-atrial pressure. In cases of mitral defects the increase of the left atrial volume and the changes in the pulse gradient of the left atrial volumes are a compensatory mechanism in the work of the left atrium.
电影心血管造影术可对左心房容积进行定量评估。发现左心房的最大容积随着二尖瓣反流的加重而增加。二尖瓣关闭不全并不总是伴有左心房的“收缩期扩张”。左心房腔的大小主要由心肌状态决定，而不太取决于心房内压力的升高。在二尖瓣缺损的情况下，左心房容积的增加以及左心房容积脉冲梯度的变化是左心房工作中的一种代偿机制。
