    INPUT: The previously seen right lower lobe opacification has decreased substantially . There has also been a mild decrease in the amount of vascular engorgement suggesting improvement in mild biventricular heart failure . In retrospect , given the rapid change , the opacification likely represented fluid overload . The heart size is at the upper limits of normal . The sternal wires are intact and midline . There is longstanding midline lucency in the manubrium and upper body is due to incomplete sternal fusion ; there is no evidence of other incision complications . A PICC can be traced to the mid SVC .
    OUTPUT:
    
1 . Mild improvement of pulmonary vascular congestion . 2 . Less opacification at the right lower ; no evidence of pneumonia on today 's radiograph . Results were communicated with the surgery team by Dr . ___ .
