Left atrial and ventricular compliance has been studied in 25 cases of chronic mitral incompetence (CMI) and 9 cases of acute mitrale incompetence (AMI). Left atrial compliance was evaluated by the ratio between maximal variation in volume and corresponding maximal variation in pressure; it was found to be higher in cases of CMI than in cases of AMI. Left ventricular compliance was evaluated by various indices (Diamond, Mirsky, Gaasch, Laird), and was found to be increased equally in the chronic and acute types. It is possible that an explanation of this increase incompliance is to be found in the rearrangement of myocardial fibres which follows the dilatation. It constitutes a fundamental means of chronic adaptation, and shows that the diastolic elastic properties of the cavities of the atrium and ventricle are as important in the evaluation of mitral incompetence as the properties of systolic contraction.
对25例慢性二尖瓣关闭不全（CMI）患者和9例急性二尖瓣关闭不全（AMI）患者的左心房和心室顺应性进行了研究。通过容积的最大变化与相应压力的最大变化之比来评估左心房顺应性；发现CMI患者的左心房顺应性高于AMI患者。通过各种指标（戴蒙德、米尔斯基、加施、莱尔德）评估左心室顺应性，发现慢性和急性类型的左心室顺应性均增加。顺应性增加的原因可能在于心肌纤维在扩张后重新排列。这是慢性适应的一种基本方式，表明心房和心室腔的舒张弹性特性在评估二尖瓣关闭不全时与收缩期收缩特性同样重要。
