    INPUT: Multiple lines and tubes have been removed including the intra-aortic balloon pump . A right IJ central line remains present , tip over upper right atrium . New compared with the prior study , there is increased retrocardiac density alteration of the left heart border consistent with left lower lobe collapse and there consolidation likely with associated small to moderate left - sided effusion . There is minimal blunting of right costophrenic angle , without gross effusion . There is minimal atelectasis at the right lung base medially . An overt CHF . No pneumothorax detected .
    OUTPUT:
    
Right IJ line remains present , tip over upper SVC . Clinical correlation regarding retraction by approximately 2 .5 cm , to lie in the lower SVC , is requested . No pneumothorax detected . Interval development of increased opacity in the left lung base , extending up to the perihilar region , likely a combination of a left pleural effusion and underlying collapse and / or pneumonic consolidation .
