摘　　要：目的比较传统二尖瓣置换术与保留后瓣及瓣下结构的二尖瓣置换术对心功能的改善情况。方法回顾过去二尖瓣置换术58例,其中传统二尖瓣置换术33例为A组,保留后瓣及瓣下结构的二尖瓣置换术25例为B组,观察围术期多巴胺使用时间、ICU停留时间、术后3个月时超声心动图测定的左心室直径、左心室舒张末期直径、左心室收缩末期直径、左射血分数、左室短轴缩短率等指标与术前对比改善情况。结果B组各项指标均优于A组。结论二尖瓣置换保留后瓣及瓣下结构有助于术后心功能改善和长期改善心功能。Objective To evaluate the improvement of mitral compared with replacement with preservation of posterior subvalvular apparatus (MVR-P) versus conventional mitral valve replacement(MVR-C) in cardiac function. Methods Retrospectively analysis was done in 58 cases treated with mitral valve replacement, 33 cases with MVR-C(group A) and 25 cases with MVR-P(group B). The time of dopamine using,ICU stay perioperation and improvement of LAD,LVEDD,LVESD,LVEF,LVFS measured by echocardiogram were observed before and three months after operation.Results All target aims of group B were better than those of group A. Conclusion Miral valve replacement with preservation of posterior subvalvular apparatus is beneficial for renewing cardiac function and for a long-term improvement of cardiac function.
