Isolated mitral insufficiency in children is quantitated angiographically by comparing the stroke volumes of the right ventricle and left ventricle. The disease results in greater enlargement of the left atrium than of the left ventricle and is accompanied by a significant increase in left atrial "distensibility." Right and left heart pressures may be normal or may be increased; they tend to be elevated in the group with regurgitant fractions of over 50%. Annuloplasty results in marked clinical and hemodynamic improvement and may even be corrective.
通过比较右心室和左心室的每搏量，对儿童孤立性二尖瓣关闭不全进行血管造影定量分析。该疾病导致左心房比左心室增大更明显，并伴有左心房“扩张性”显著增加。左右心压力可能正常或升高；反流分数超过50%的患者组中压力往往升高。瓣环成形术可使临床和血流动力学得到显著改善，甚至可能具有矫正作用。
