Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Multiple median sternotomy wires are identified . The cardiomediastinal silhouettes are stable , within normal limits . The bilateral hila are unremarkable . Slight opacity at the right cardiophrenic angle likely reflects crowding of normal bronchovascular structures . Otherwise , the lungs are clear without focal consolidation . Mild interstitial prominence , with prominent interlobular septa , is compatible with pulmonary vascular congestion . There is no frank pulmonary edema . There is no pleural effusion or pneumothorax .
    OUTPUT:
    
Pulmonary vascular congestion without frank pulmonary edema . No effusions .
