Abstract:
The antero-posterior chest rcentgenogram of mitral valve disease before and after valve prosthesis were presented for the preliminary evaluation of the surgical effects. The criteria included cardio-thoracic ratio, DPA/DHT X 100, diameter of Rt descending oranch of pulmonary artery, diameter of Rt upper pulmonary vein, total huar width, pulmonary hypertension, changes of pulmonary artery tributaries, K-B line, interlobar pleural thickening and pleural effusion. 15 cases of mitral valve dilation were selected randomly for control.

Statistical-ly most criteria showed P
