Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There is increased near complete opacification of the right hemithorax without new shift of the mediastinum . There is no pneumothorax . A Swan - Ganz catheter projects over the proximal right pulmonary artery . Increased interstitial opacities in the left lung are most likely due to pulmonary edema . A stable retrocardiac airspace opacification is most likely due to atelectasis . The intra-aortic balloon pump tip is within 1 cm of the upper aspect of the aortic arch . A new layering left pleural effusion is small .
    OUTPUT:
    
Increased near complete opacification of the right hemithorax is most likely due to a combination of atelectasis and large pleural effusion . New mild pulmonary edema . New small left pleural effusion with increased partial left lower lobe collapse . High - riding IABP should be retracted by 2 cm for more optimal positioning .
