    INPUT: Frontal and lateral views of the chest were obtained . Dual - lead left - sided pacemaker is again seen with leads in the expected positions of the right atrium and right ventricle . Bibasilar opacities are again seen , likely a combination of pleural effusions and atelectasis ; however , underlying consolidation is not excluded . Perihilar opacities / prominence of the hila likely relate to underlying pulmonary edema , which appears mildly improved as compared to the prior study . The cardiac silhouette remains enlarged . The aortic knob is calcified .
    OUTPUT:
    
Persistent bibasilar opacities may represent combination of pleural effusions and atelectasis , underlying consolidation not entirely excluded . Enlargement of the cardiac silhouette . Pulmonary edema , somewhat improved from the prior study .
