Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Heart size remains markedly enlarged , unchanged . The aorta is diffusely calcified and mildly tortuous , also unchanged . Left - sided pacemaker device is re - demonstrated with leads terminating in the right atrium , right ventricle , and coronary sinus . Abandoned right - sided pacemaker lead is again seen . Mild pulmonary vascular congestion is present , mildly increased compared to the prior exam . Small right pleural effusion also appears slightly increased compared to the prior exam with associated right basilar opacification likely reflective of atelectasis . Minimal left pleural effusion is likely present . No pneumothorax is identified . Dextroscoliosis of the thoracic spine is again seen .
    OUTPUT:
    
Small bilateral pleural effusions , right greater than left , without interval increase in size of the right pleural effusion . Right basilar opacity likely reflects atelectasis though infection can not be excluded . Slight interval increase in extent of pulmonary vascular congestion .
