Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There is very slight rotated positioning . Multiple lines and tubes are present , nominal in position . The right IJ Swan - Ganz catheter tip may lie in the RV or at the origin of the pulmonary outflow tract . No pneumothorax detected . Again seen is cardiomegaly , with sternotomy wires and prosthetic valve . The aortic valve is indistinct , but not clearly changed compared with the most recent prior film . Equivocal slight convexity is seen in the region of the aortopulmonary window , in the setting of air bronchograms and consolidation around the lobar and segmental airways . Mild vascular plethora is again noted , grossly unchanged . Also again seen is left lower lobe collapse and / or consolidation , with obscuration left hemidiaphragm . This has probably increased slightly compare with the prior film . The possibility of a small left effusion can not be excluded . Minimal atelectasis at the right base is slightly increased . No gross effusion identified .
    OUTPUT:
    
1 . Lines and tubes as described . 2 . Cardiomediastinal silhouette , including indistinctness of the aortic arch , is grossly unchanged . Question minimal new convexity in the aortopulmonary window . 3 . Left lower lobe collapse and / or consolidation may be slightly worse . 4 . Minimal atelectasis at the right base is slightly increased . 5 . No gross pleural effusion is seen on either side . 6 . Mild vascular plethora is grossly unchanged .
