The relationship of roentgenographic findings and pulmonary arterial pressure was studied upon the 20 patients with mitral srenosis and compared it with normal cases.
In this study it was proved that Kerley-B-line, perivascular haziness, and promonent reticulation in lower pulmonary lobe often found in the cases of mitral stenosis accompanied with pulmonary hypertension, but not in the cases with normal pulmonary pressure.
Bulging of the pulmonary arterial segment and enlarged right hilar shadow were found in almost everyy cases. About these roentgenographies, geometrical studies were performed using 1/2 trans thoracic diameter, the diameter of pulmonaty arterial segment in the cardiac silhouette and the size of most prominent point on the left cardiac border. The relationship of pulmonary hypertension and roentgenographic findings were discussed in each case. And also discussed about the causes of roentgenographic f alse-diagmosis between mitral stenosis and lung-diseases.
