    INPUT: A chronic moderate right pleural effusion with probable associated atelectasis appears unchanged from prior examination . Diffuse interstitial opacities are stable and likely reflect chronic mild edema . Unchanged minimal blunting of the left costophrenic angle suggests a small left effusion as well . There is no pneumothorax . Enlargement of the cardiomediastinal contours is unchanged . The pacemaker generator and leads appear in standard position terminating in the expected location of the right atrium and right ventricle .
    OUTPUT:
    
1 . Unchanged chronic mild interstitial edema with stable moderate right pleural effusion . 2 . Unchanged moderate cardiomegaly .
