摘要(Abstract)：
<正> Many papers have demonstrated that perctaneous transvenous nitralcolnmissurotomy(PTMC)can improve patterns' heart function.The aim of thisresearch is to confirm the effect of PTMC on pulmonary function of rheumaticheart disease.PTMC was performed in 40 mitral stenosis patients according toInoue's method.Left atrium mean pressure(LAMP),left ventricular diastolicend pressure(LVDEP),mean pressure gradient across the mitral valve(MVG)and right ventricular systolic prossure(RVSP)were measured immediatelybefore and after dilatation ofmitral valve,Pulmonary function,including VCFEV_(10)/FVC、TLC、RV/TLC/、V_(50)、V_(25) as percent predicted valuerespectively(VC%、FEV_(10)/FVC%、TLC%、RV/TLC%、V_(50)%,、V_(25)%)were also dtermined in one week before and after PTMC,All cardiac pressureindexes and mitral valve area(MVA)were improved(P<0.01)and dates ofVC%,V_(50)% were higher(from 76.54、79.59 to 84.33.93.29)andRV/TLC% was lower(from 147.12 to 129.82)dramstically(P<0.01)after PTMCFEV_(10)/FVC%、TLC% and V_(25)% were normal before PTMC and did notchange clearly.From this datas,we concluded that the patients suffered fromrheumatic mitral stenosis had clear decrease in pulmonary function and PTMCcould improve it obviously.
