    INPUT: The pacer unit leads are unchanged in position . The endotracheal tube tip sits 3 cm above the carina . The endogastric tube side port sits just below the GE junction . A prosthetic mitral valve is noted . The heart size is stable . There has been minimal improvement in the diffuse ground - glass opacities . Blunting of both costophrenic angles suggests small pleural effusions along with predominantly retrocardiac atelectasis . There is no pneumothorax .
    OUTPUT:
    
Slightly improved pulmonary opacities compatible with moderate pulmonary edema versus pulmonary hemorrhage .
