title: [X-ray diagnosis of pulmonary hypertension in mitral valve defects].
abstract: Quantitative roentgenologic criteria of lung hypertension are compared with pressure values from intracardiac catheters for 149 patients with mitral disorder. For chronic rheumatic mitral disorders the nature of the valve lesion cannot be determined from the lung vessel pattern. It was found that quantitative criteria facilitate the diagnosis of lung hypertension in 91% of the cases. The most significant and safe criterium is the diameter of the pulmonary artery over the left main bronchus.
