Summarize the radiology report findings into an impression within 3 sentences.
    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 ___ . Position of previously described left - sided permanent pacer connected to two intracavitary electrodes remains unchanged . Heart size has increased mildly . The thoracic aorta is unchanged and shows rather extensive walled calcifications mostly at the level of the arch . It is also moderately elongated but the contours are grossly unchanged . The pulmonary vasculature is more prominent than on preceding examination with distended venous vasculature in the lungs with perivascular haze . Similar as already seen on previous examination , there exist thin linear densities on the bases representing peripheral atelectasis or possibly scar formations . They are rather unchanged and there is no evidence of new discrete pneumonic infiltrates . Also , the lateral and posterior pleural sinuses remain free from any major fluid accumulation . No pneumothorax is seen in the apical area . Skeletal structures of the thorax are grossly unchanged and remain normal .
    OUTPUT:
    
Slightly increasing heart size and moderately distended pulmonary vascular pattern indicative of mild degree of chronic left - sided failure . Comparison shows the patient is more congested than she was on previous examination in ___ . Efforts with dehydration therapy will probably correct this finding which could be documented on a followup chest examination in a week or two of so required .
