Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Frontal and lateral views of the chest were obtained . Dual - lead left - sided pacemaker is again seen with leads extending to the expected positions of the right atrium and right ventricle . The lungs are hyperinflated , with flattening of the diaphragms , suggesting chronic obstructive pulmonary disease . No pleural effusion or pneumothorax is seen . Slight increased opacity at the right lung base , best seen on the frontal view may relate to atelectasis , although in the appropriate clinical setting , infectious process is not excluded . No overt pulmonary edema is seen . Chest radiography is inappropriate for evaluation of pulmonary embolism . The aorta is calcified and tortuous . The cardiac silhouette is top normal to mildly enlarge .
    OUTPUT:
    
1 . Hyperinflated lungs suggest chronic obstructive pulmonary disease . 2 . Slight increase in opacity at the right lung base may relate to atelectasis , although in the appropriate clinical setting , infectious process is not excluded .
