Methods By directly integrating the mitral regurgitant jet in space and in time during the systole, 19 patients with eccentric MR were examined by the modified ACOM, and the severity of the 19 patients using RV as evaluation parameter was graded.

• 方法对19例患偏心性反流患者采用ACOM改进法,于收缩相对经二尖瓣反流瓣口的血流速度直接进行时间和空间双重积分,得到二尖瓣反流量,并将反流量作为评价参数,对患者的反流严重程度进行划分。
