    INPUT: A three - lead pacemaker / ICD device with leads terminating in the right atrium , right ventricle , and coronary sinus , respectively , appears unchanged . The heart is moderately enlarged . The cardiac , mediastinal and hilar contours appear stable . There is no pleural effusion or pneumothorax . Upper zone re-distribution of pulmonary vascularity and indistinct pulmonary vessels , as well as a mild interstitial process , suggest mild vascular congestion , similar to mildly increased . Streaky superimposed right mid lung opacities are suggestive of atelectasis .
    OUTPUT:
    
Mild pulmonary vascular congestion . Streaky focal opacities projecting over the right mid lung , although suspected to represent atelectasis . If clinical findings are suggestive of infection in addition to congestive heart failure , then short - term radiographs may be helpful to re-assess .
