The vertical dimension of the heart is slightly increased. The area of the cranial waist is normal . The cranial lobar vessels are difficult to visualize but appear small. The pulmonary vasculature is difficult to visualize due to the overwhelming peribronchial pattern. There is more evidence of peribronchial changes .
Pulmonary edema does present with a prominent peribronchial pattern.
Usually patches of alveolar changes are detected as well. Marked left atrial enlargement. This is a result of the chronic mitral valve insufficiency. Note that we have no evidence of bronchial compression secondary to left atrial enlargement. Left ventricular enlargement.
