摘　　要：目的:探讨心脏瓣膜替换术后影像学变化与心功能改善之间的变化规律。方法:对45例风湿性心脏病(RHD)患者术前、术后的胸部X线平片、心脏超声、心功能分级进行手术前后对比。结果:45例患者术后肺纹理均明显减少,心胸比率缩小。左室舒张末期直径、左房舒张末期前后径均有所减小,左室射血分数(LVEF)以狭窄为主的25例中平均升高12%,以关闭不全为主的20例中LVEF变化不明显9例,升高者11例;NYHA心功能分级:Ⅱ级34例,Ⅲ级11例。结论:术后胸部X线平片、心脏超声检查显示改善明显者,心功能恢复良好,疗效显著。Objective： To explore the rule between imaging change and cardiac function improvememt in postoperafion of valve replacement. Methods： Chest X-ray film, Echocardiography and classification of cardiac function were compared in 45 cases of rheumatic heart disease（RHD） during before operation and postoperafion. Results：Chest X-ray film in postoperation is better than before. The end-diastolic diameter of left ventricle,left atrium were smaLler,left ventricular ejection fraction was higher 12 percent than before in 25 cases, but in another 20 cases LVEF was same as before in 9 cases and higher in 11eases. Cardiac function classification by NYHA：grade Ⅱin 34 cases,grade Ⅲ in 11 cases. Conclusion： Imaging change was obvious in postoperation, cardiac function and clinical curative was better than before.
