Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Moderate left and small right pleural effusions with associated compressive atelectasis are essentially unchanged . Opacity projecting over the right apex was not clearly seen on prior radiographs . There is no widening of the paratracheal stripe to suggest mediastinal hematoma . Lungs are otherwise clear . A small left apical pneumothorax is new . A right IJ central venous catheter is unchanged in position , terminating near the superior cavoatrial junction . Moderate cardiomegaly is unchanged . Visualized cardiomediastinal hilar silhouettes are unremarkable . A mitral valve replacement is noted . Median sternotomy wires are midline and intact .
    OUTPUT:
    
1 . New small left apical pneumothorax . 2 . Right apical opacity raises the possibility of pleural fluid or blood . 3 . Unchanged moderate left and small right pleural effusions with associated compressive atelectasis .
