    INPUT: Moderate - to - severe cardiomegaly is unchanged compared to the prior study . The aorta remains calcified and tortuous . There is mild pulmonary edema , slightly worse in the interval , with continued patchy opacities in the lung bases which are nonspecific . Minimal blunting of the right costophrenic angle suggests a trace pleural effusion . The left costophrenic angle is excluded from the field of view . No pneumothorax is identified .
    OUTPUT:
    
Mild congestive heart failure , slightly worse when compared to the most recent prior study , with trace right pleural effusion . Left costophrenic angle is excluded from the field of view . Patchy bibasilar opacities are nonspecific but may reflect atelectasis , or recurrent aspiration or infection .
