    INPUT: Portable upright AP chest radiograph demonstrates an enlarged heart . A left chest pacer defibrillator device is present , its leads which appear intact in the in stable configuration relative to prior examination . There has been interval placement of a left internal jugular Cordis , its tip which projects more inferiorly than the expected location of the brachiocephalic vein . There is no pneumothorax . A right PICC terminates within the low superior vena cava . There is no large pleural effusion . Central vascular engorgement is mild . No focal consolidation is identified convincing for pneumonia given low lung volumes , portable technique and patient body habitus .
    OUTPUT:
    
Moderate cardiomegaly . Interval placement of a left internal jugular Cordis without pneumothorax . Exact location difficult to delineate , its tip which projects somewhat more inferiorly than expected location of brachiocephalic . Clinical correlation with blood gas to ensure venous placement or alternatively lateral may be helpful for further evaluation .
