Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Frontal and lateral views of the chest were obtained . The patient is status post median sternotomy and CABG . Again , there is blunting of bilateral costophrenic angles , suggesting small bilateral pleural effusions . There is also moderate central pulmonary vascular engorgement and bibasilar atelectasis . Retrocardiac opacity on the lateral view likely relates to small pleural effusions with overlying atelectasis , although underlying consolidation can not be entirely excluded . No pneumothorax is seen . The cardiac silhouette remains mildly enlarged . The aortic knob is calcified .
    OUTPUT:
    
1 . Small bilateral pleural effusions and moderate central pulmonary vascular engorgement . 2 . Retrocardiac opacity seen on the lateral view most likely relates to pleural effusions and atelectasis , although underlying consolidation can not be excluded . 3 . Cardiomegaly .
