ABSTRACT
Objective:To investigate the relationshipe and role of front cardiac film,left bariumswallowed film and colour Doppler ultrasound in Inoue balloon dilatation of patients with mitral valve stenosis in rheumatic heart diseas.Methods:The examined results of 136 cases were compared.Results:The signs of mitral valve stenosis in rheumatic heart disease might be observed by the front cardiac film and left barium-swallowed film,and the above-mentioned films could instruct to puncture foramen ovale in Inoue balloon dilatation.Howeuer,it couldn′t evaluate the degree of mitral valve stenosis.There was no relation-shipe between the size of cardiac shadow,left atrial and the narrow degree of mitral valve entrance.The condition of patient ofter operation can be judged by comparing the finding on the pre-and postoperational films,and the size of the mitral valve entrance atrials and ventriculars,and the condition of blood flow can be judged by colour Doppler ultrasound before surgery,so that it can provide reliable data for operation.Conclusion:The combination of both radiography and ultrasound is absolutely necessary in Inoue balloon dilatation of patients with mitral valve stenosis in rheumatic heart disease.
