目的：观察对风湿性心脏病患者采用保留二尖瓣装置的换瓣术进行治疗的临床疗效。方法选择我院2013年2月至2015年2月间接诊的90例风湿性心脏病患者，随机分为两组各45例。治疗组患者给予保留二尖瓣装置的换瓣术进行治疗，对照组患者使用不保留二尖瓣装置的换瓣术进行治疗。观察及对比两组的临床疗效。结果治疗组患者治疗后的心功能分级情况显著优于对照组，差异有统计学意义（P<0.05)。治疗组治疗后的LVEDD、 LVESD显著低于对照组， FS、 EF显著高于对照组，差异有统计学意义（P<0.05)。结论保留二尖瓣装置的换瓣术可有效改善患者的心功能，提高患者术后左心室的舒张、收缩、射血能力，从而有效促进患者的术后康复。%Objective To observe and analyze the clinical effect of mitral valve replacement with preservation of mitral apparatus for treatment of rheumatic heart disease. Methods A total of 90 cases of patients with rheumatic heart disease admitted to our hospital from February 2013 to February 2015 were selected and randomly divided into two groups. The treatment group received mitral valve replacement with preservation of mitral apparatus, while the control group received mitral valve replacement without preservation of mitral apparatus. The clinical effects of two groups were compared. Results After treatment, the cardiac function classification of treatment group was significantly better than that of control group (P<0.05), the LVEDD and LVESD were significantly lower than those of control group (P<0.05), and the FS and EF were significantly higher than those of control group (P<0.05). Conclusions Mitral valve replacement with preservation of mitral apparatus for treatment of rheumatic heart disease can effectively improve the heart function of patients, and improve the diastolic, systolic, ejection capability of left ventricle after operation, so as to promote the postoperative recovery of patients.
