Can the appearance of pulmonary veins on posteroanterior film estimate left atrial pressure in patients with rheumatic valvular heart disease?
The appearance of pulmonary veins on posteroanterior chest films can be used to accurately estimate left atrial pressure in patients with rheumatic valvular heart disease.
Ormond et al. (1960) conducted an observational in Rheumatic valvular heart disease. Left atrial pressure was evaluated on Appearance and size of pulmonary veins on posteroanterior film. The size of upper lobe pulmonary veins on posteroanterior films correlates with left atrial pressure in rheumatic valvular heart disease, allowing accurate estimation of pressure groups.
