Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: AP single view of the chest has been obtained with patient in supine position . Comparison is made with the next preceding portable chest examination of ___ . Again marked cardiomegaly is identified and rather advanced dens calcifications occupy the mitral ring area . The latter finding matches the previous torso CT identified cardiac changes which included marked enlargement of the left atrium . The pulmonary vasculature is somewhat congested , but not significantly more than it was on the preceding study . The same holds for the hazy density on the lung bases and particularly on the left side over the whole hemithorax compatible with pleural effusions layering the posterior pleural spaces as the patient is placed supine . No significant interval change can be identified . There is no pneumothorax .
    OUTPUT:
    
Stable chest findings over the latest two days ' examination interval . The patient had now more than ___ chest examinations over the last period , none of which included a lateral view . The lateral might be useful to document truly the amount of pleural effusion that might have accumulated posteriorly . Previously described right - sided PICC line appears unchanged , although it is very difficult to identify on this portable chest examination .
