Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The intra-aortic balloon pump ends 2 .2 cm below the aortic knob and 1 .8 cm above the left mainstem which is adequate but should not be higher . Right - sided Swan - Ganz has been slightly pulled back and now ends in the right pulmonary artery . Moderate pulmonary edema , more localized in the right upper lobe may be due to mitral valve regurgitation . Prior sternotomy was done for mitral valve repair in this patient with significant cardiomegaly . There is no pleural effusion or pneumothorax . New 18 mm very dense opacity is seen in the left upper quadrant , probably in the stomach which could represent ingested pill or even a tooth .
    OUTPUT:
