Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The cardiomediastinal and hilar contours are stable with moderate cardiomegaly . Right basilar opacity is likely a reflection of pleural effusion and atelectasis , increased compared the prior study , although underlying consolidation is not excluded . There is no significant left pleural effusion . There is no pneumothorax . Right upper paramediastinal density appears smaller compared to prior and is likely related to prior VATS . Pulmonary edema is worsened compared to the most recent prior study and is moderate to severe . Left chest wall dual lead pacemaker defibrillator is present with tip terminating in the right atrium and right ventricle as expected .
    OUTPUT:
    
Moderate pulmonary edema with right basilar opacity , likely a combination of pleural effusion and atelectasis , although underlying consolidation is not excluded .
