    INPUT: PA and lateral chest views were obtained with patient in upright position . Analysis is performed in direct comparison with the next preceding similar study of ___ . Again mild cardiac enlargement is present . The thoracic aorta is moderately widened and elongated and shows calcium deposits in the wall mostly at the level of the arch . A permanent pacer is again noticed in left anterior axillary position connected to dual intracavitary electrodes , one of which is an ICD device . Termination points of electrodes are unchanged . The pulmonary vasculature demonstrates features of mild - to - moderate degree of chronic congestion with upper zone redistribution , perivascular haze and some increased interstitial markings mostly on the bases . New discrete parenchymal abnormalities can not be identified and the lateral and posterior pleural sinuses remain free from any significant fluid accumulation . No pneumothorax has developed in the apical area . Skeletal structures of the thorax also remain unchanged . Comparison is extended to a chest examination of ___ at which time the patient was somewhat more congested . Review was also undertaken of the chest CT ___ ___ which confirmed the described chronic pulmonary changes but excluded any local abnormalities .
    OUTPUT:
    
Mild - to - moderate cardiac enlargement stable , unchanged position of permanent pacer and ICD device , mild degree of chronic pulmonary congestion but absence of new acute infiltrates or significant pleural effusion .
