    INPUT: PA and lateral chest views were obtained with patient in upright position . The heart size is normal . No configurational abnormality is identified . Unremarkable appearance of thoracic aorta . The pulmonary vasculature is not congested . No signs of acute or chronic parenchymal infiltrates are present and the lateral and posterior pleural sinuses are free . No pneumothorax in the apical area . Somewhat low - positioned diaphragms and lucent appearance of lung bases suggest possibility of COPD , but again acute infiltrates can not be seen . Within the normal heart shadow , the lateral view discloses typical track - shaped calcifications in antero and left - sided position within the heart shadow identifying the left anterior descending artery . No other intracardiac calcifications are identified . Our records do not include a previous chest examination available for comparison .
    OUTPUT:
    
Normal heart size , no evidence of pulmonary congestion , unremarkable appearance of thoracic aorta , but extensive calcifications in the area of the LAD .
