    INPUT: Since the prior exam , the Swan - Ganz catheter has been slightly withdrawn , but it still ends in the proximal left pulmonary artery . The patient has had recent sternotomy with aortic valve replacement . Sternotomy wires are intact and aligned . The side port of the enteric tube sits at the GE junction . Advancement by at least 5 cm should be considered for more optimal positioning within the stomach . Remaining support devices , including an ET tube and mediastinal drain remain in satisfactory position . The lungs are clear . There is no pneumothorax . Mild cardiomegaly despite the projection is unchanged .
