Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The patient remains intubated . An orogastric tube courses into the stomach . A single - lead pacemaker , inserted via the inferior vena cava , terminates in the right ventricle , as before , and there is also a right internal jugular central venous catheter terminating at the cavoatrial junction . An aortic balloon pump has been removed . The cardiac , mediastinal and hilar contours appear unchanged . Although a right perihilar opacity referring either to the right middle or lower lobe has substantially improved , there is an increased interstitial prominence suggesting mild vascular congestion , in addition to suspicion for a layering pleural effusion on the right , probably small to small - to - moderate in size . A retrocardiac opacity has increased , which is most commonly due to atelectasis .
    OUTPUT:
    
Removal of aortic balloon pump . Findings suggesting mild increased pulmonary vascular congestion . Suspected layering right - sided pleural effusion . Increased retrocardiac opacity , effacing the left hemidiaphragm , commonly due to atelectasis .
