Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A single frontal view of the chest was obtained portably . Low lung volumes results in bronchovascular crowding . There is no focal consolidation , pleural effusion or pneumothorax . Moderate to severe cardiomegaly is unchanged , allowing for differences in lung volumes . Mild pulmonary vascular congestion without overt pulmonary edema is seen . The right hilum is slightly dense , which may be due to lung volumes . Median sternotomy wires are intact .
    OUTPUT:
    
1 . Pulmonary vascular congestion without overt pulmonary edema . 2 . Dense right hilum may be due to low lung volumes . Recommend repeat conventional PA and lateral radiographs for further evaluation once acute issues have resolved .
