Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: An ET tube is present . The tip lies at the level of mid clavicular heads are of the carina . An NG tube is present . The tip extends beneath the diaphragm , off the film . An apparent intra-aortic balloon pump is present . The radiopaque tip overlies the upper edge of the aortic arch -- clinical correlation regarding retraction by approximately 3 cm to lie in the proximal descending aorta is requested . Faint cylindrical density overlying the thoracic spine at the level of the aortic arch likely represents material outside the patient . Heart size is at the upper limits of normal or minimally enlarged . Vascular plethora and diffusely increased interstitial markings is present . This could represent CHF with interstitial edema , though a diffuse interstitial process could have a similar appearance . There is subsegmental atelectasis at both lung bases . No gross effusion .
    OUTPUT:
    
ET tube 6 .1 cm above the carina . Radiopaque tip of an intra-articular balloon pump overlies the upper edge of the aortic arch . Clinical correlation regarding retraction into the proximal descending aorta by approximately 3 cm is requested . Diffusely increased interstitial markings and bibasilar atelectasis . The appearance is compatible with CHF , though a diffuse interstitial process could have a similar appearance . No gross effusions .
