Hemodynamic disorders which developed in 12 patients with artificial mitral incompetence were studied. A method developed in the clinic of analysing the findings of catheterization and cine-angiocardiography was used. The method of analysis of single-plane ventriculograms makes it possible to estimate the volume of blood regurgitated into the left atrium to an accuracy of several millilitres. The degree of artificial incompetence is determined from the relative regurgitation which is estimated by dividing the volume of returned blood flow by the total volume of ventricular ejection. It is concluded that the "malignancy" of the course of artificial incompetence is determined by a sharp reduction of the effective cardiac output (to 33--50% of the normal volume) against the background of rapid rapid exhaustion of the left ventricular myocardum.
对12例人工二尖瓣关闭不全患者所出现的血液动力学紊乱进行了研究。采用了临床所开发的一种分析心导管检查和电影心血管造影检查结果的方法。单平面心室造影图的分析方法能够精确到几毫升来估计反流回左心房的血液量。人工关闭不全的程度由相对反流来确定，相对反流通过将回流血液量除以心室射血总量来估算。得出的结论是，人工关闭不全病程的“严重性”取决于在左心室心肌迅速耗竭的背景下有效心输出量急剧减少（降至正常量的33%-50%）。
