    INPUT: There has been interval placement of intra-aortic balloon pump , with radiopaque tip projecting over the descending aorta at the level of the left mainstem bronchus ; this could be advanced forward approximately 3 cm for ideal positioning . The patient is now intubated , with distal tip of ET tube projecting below the level of the clavicles , approximately 4 .8 cm above the carina . A right IJ central catheter is again seen with distal tip in stable position in the mid SVC . The cardio mediastinal silhouettes are stable in appearance , with re-demonstrated cardiomegaly . There is improvement in the appearance of pulmonary vascular congestion . There is evidence of persistent probably small bilateral pleural effusions , posteriorly layering on the current film . There is relaxation atelectasis of bilateral lower lobes as seen previously . There is no pneumothorax .
    OUTPUT:
    
1 . Intra-aortic balloon pump at the level of left mainstem bronchus . Could be advanced 3 cm for ideal positioning . 2 . Improvement in pulmonary vascular congestion . Stable small bilateral pleural effusions and adjacent bibasilar atelectasis .
