Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The patient has been extubated and the NGT removed in the interim since the most recent prior study . A left pectoral pacemaker is unchanged with two leads terminating in the right atrium and apex of the right ventricle , unchanged from the preceding study . A right internal jugular Swan - Ganz catheter is unchanged in position with the tip in the main pulmonary artery . A right apical chest tube is in place . There is no pneumothorax . There is patchy opacification of the right lung compared to the left and a small right pleural effusion is present . The right hemidiaphragm is elevated compared to the left . The cardiac silhouette remains enlarged but stable . The patient is status post median sternotomy with multiple mediastinal surgical clips , compatible with prior coronary artery bypass graft surgery . A CoreValve stent projects over the aorta , unchanged .
    OUTPUT:
    
1 . Unchanged position of dual - channel pacer leads . 2 . Interval removal of ET and NG tubes with otherwise stable placement of support devices . 3 . Opacification of the right lung with elevated right hemidiaphragm likely reflects a combination of pleural fluid , atelectasis and possible asymmetric pulmonary edema .
