Résumé : The authors correlated the capillary pressures predicted by analysis of the erect standard thorax view with the catheterization findings in 63 patients. A capillary pressure schedule is proposed, based on radiological identification of apical vascular redistribution and interstitial and alveolar edema. Good correlation was established in 80% of cases for pressure values between 12 and 30 mmHg. Patients presenting vascular redistribution and radiological evidence of pulmonary arterial hypertension are considered separately. Plain chest film would seem to be a valuable diagnostic aid in predicting pulmonary capillary pressures.
