“…The shape of the curve is in all similar to that described by Moore et al [18] and Milne [19] in isolated mitral stenosis, and closely resembles the relationship between pulmonary distending pressure and pulmonary blood volume in humans receiving dextran infusion and subsequent atropine injection [26]. Thus, the normalized width of the main pulmonary artery can be regarded as an index of pulmonary vascular distensibility in response to an elevation of MPAP.…”

“…Some early studies, published long before the introduction of echocardiography, showed that measuring the width of the main pulmonary artery, as percentage of the width of left hemithorax (MPA/LH ratio), provides a crude but clinically valuable estimation of MPAP [18][19][20]. Such studies focused on the evaluation of patients with pure mitral stenosis.…”

“…Symmetric dilatation of the arteries and veins of the upper lobes with reduction in caliber of the lower lobe vessels was recorded as "dilated upper lobe vessels". This indicates redistribution of pulmonary blood flow to non-dependent lung regions, and it is often seen in patients with chronic LHF, or left heart valvular disease [18][19][20].…”

“…In the postero-anterior view, the width of the main pulmonary artery was estimated by measuring the linear distance between the outermost border of the vessel and the midline of the chest [18][19][20]. When the main pulmonary artery was straight or slightly concave, the measurement was made from a point of its border midway between the aortic knob and the left atrial appendage [18][19][20].…”

“…The width of the main pulmonary artery was estimated in the frontal chest radiograph, and was plotted against MPAP measured at RHC in 165 patients [18][19][20]. Details are given in the Appendix A.…”

a b s t r a c t a r t i c l e i n f oObjective: To assess the accuracy of chest radiography (CXR) in predicting pulmonary hypertension (PH). Methods: We studied 108 consecutive patients with suspected PH who underwent right heart catheterization (RHC). All were PH treatment naives. Hemodynamic criteria included a mean pulmonary artery pressure N 25 mmHg at rest, and a mean pulmonary wedge pressure b 15 mmHg. Postero-anterior and lateral CXR were obtained shortly before RHC. To avoid a selection bias which could be introduced by examining only patients with suspected PH, we included in the analysis the CXR of 454 additional patients with different diagnosis: 57 with left heart failure (LHF) and pulmonary venous hypertension at RHC, 197 with chronic obstructive pulmonary disease, and 200 non-obstructed controls. CXR were examined independently by 4 raters, who were blinded to clinical, hemodynamic, and spirometric data. The diagnosis of PH was made if a prominent main pulmonary artery was associated with anyone of: isolated enlargement of right ventricle, right descending pulmonary artery N 16 mm in diameter, pruning of peripheral pulmonary vessels. Results: Eighty-two patients had PH confirmed at RHC. Weighted sensitivity of CXR was 96.9% (95% confidence interval, 94.9 to 98.2%), and weighted specificity 99.8% (95% confidence interval, 99.6 to 99.9%). By considering the 165 patients who underwent RHC, weighted sensitivity of CXR was unchanged, and weighted specificity decreased to 99.1%. None of the patients with PH were misclassified as having LHF, and vice versa. Conclusions: CXR is accurate in predicting PH. It may aid clinicians in selecting patients with suspected PH for hemodynamic ascertainment.

Summary:Plain chest x-rays, twelve-lead elecmcardiograms, and M-mode echocardiograms were analyzed in 50 control patients and 79 consecutive patients with pulmonary hypertension documented at cardiac catheterization in onder to determine the relative values of these noninvasive techniques as screening tests in detecting pulmonary hypertension. The sensitivity and specificity of selected findings previously described as being associated with pulmonary hypertension were calculated for each test, All test results were found to have sensitivities too low to function as satisfactory noninvasive screening techniques. Most findings were highly specific for pulmonary hypertension when present. Patients with pulmonary vascular disease were detected more frequently than those with pulmonary hypertension due to pulmonary venous congestion.
