Key result
A comparative increase of upper lobe pulmonary vein size was demonstrated in 80% of patients with mitral stenosis and 39% of patients with left ventricular failure.
Why the study?
Does tomographic measurement of pulmonary veins show differences in upper lobe vein size in patients with mitral stenosis or left ventricular failure compared to normals?

Upper lobe vein enlargement on tomography was more frequent in mitral stenosis; leaves open its diagnostic utility for differentiating pulmonary venous hypertension.

Does tomographic measurement of pulmonary veins show differences in upper lobe vein size in patients with mitral stenosis or left ventricular failure compared to normals?
Tomographic measurement of pulmonary veins reveals a comparative increase in upper lobe vein size in 80% of patients with mitral stenosis and 39% with left ventricular failure, suggesting similar hemodynamic mechanisms.
Lavender et al. (1962) conducted a cross-sectional in Mitral stenosis and left ventricular failure (n=129). Mitral stenosis and left ventricular failure vs. Normal subjects was evaluated on Comparative increase of upper lobe vein size. A comparative increase of upper lobe pulmonary vein size was demonstrated in 80% of patients with mitral stenosis and 39% of patients with left ventricular failure.
