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 dated ___ . The overall heart size is at the upper limit of normal variation . No typical configurational abnormality is identified . There is a relative prominence of the left ventricular contour to the left and posteriorly but no signs of significant left atrial enlargement is present . The thoracic aorta is generally moderately widened and shows extensive wall calcifications predominantly in the arch , but also extending into the descending aorta . On the lateral view , the typical calcifications in the aortic valve are identified . A permanent pacer is located in left anterior axillary position that is connected to two intracavitary electrodes , one of which terminates towards the right atrial appendage , the second terminates in the apical portion of the right ventricle . These findings are stable when compared with the next preceding examination when the patient had to be examined in sitting semi-upright position using AP frontal projection view . The latter finding explains that the heart shadow appeared somewhat larger than it is now . Pulmonary vasculature is not congested and there is no evidence of any acute or chronic parenchymal infiltrates . Lateral and posterior pleural sinuses are free and no pneumothorax is identified in the apical area .
    OUTPUT:
    
Stable chest findings in elderly female patient with permanent pacer , dual electrodes in place , borderline heart size but no evidence of pulmonary vascular congestion or any acute infiltrates . Extensive aortic wall calcifications and calcium deposits in the aortic valve area already seen on previous examinations .
