    INPUT: A new drainage catheter projects over the mid hemithorax . An associated fluid collection appears decreased but a small opacity suggesting residual fluid projecting over the right mid hemithorax . Two drainage catheters projecting over the left mid - to - lower hemithorax appear unchanged with persistent widespread retrocardiac opacification and probably a residual small pleural effusion . Left perihilar opacity is stable . Streaky opacities at the right base remain , but for the most part , aeration has improved substantially in the right lower lung . A PICC line courses into the superior vena cava from a right - sided approach . It s tip is difficult to visualize because of coinciding three - lead pacemaker / ICD device , but it probably terminates in the superior vena cava .
    OUTPUT:
    
Interval placement of posterior drainage tube along the mid right hemithorax with decreased fluid . Improved aeration at the right lung base .
