    INPUT: Evaluation of the lung fields is limited due to respiratory motion . The right lung is well aerated . New increased perihilar opacity and peribronchial cuffing in the left perihilar region is consistent with interval development of heart failure . Retrocardiac opacities are compatible with the known hiatal hernia . No pleural effusions or pneumothorax are identified . The heart size is difficult to determine , but likely mildly enlarged . The aortic knob is calcified . Eventration of the right hemidiaphragm is chronic .
    OUTPUT:
    
New peribronchial cuffing and perihilar opacity are consistent with interval development of heart failure .
