Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: PA and lateral chest views were obtained with patient in upright position . There is cardiomegaly . The enlargement appears to involve mostly the left ventricle which is prominent to the left and posteriorly . Thoracic aorta is moderately widened but markedly elongated and shows some calcium deposits in the wall at the level of the arch . Pulmonary vasculature is presently not congested . There exists some prominence of the central pulmonary artery , the hilar regions , but the periphery does not show perivascular haze nor is there evidence of interstitial or alveolar edema . The lateral and posterior pleural sinuses are free , excluding significant pleural effusion . No acute parenchymal infiltrates are identified . Comparison can be made with the frontal view of a preceding chest examination , outside institution . On this image , poor inspirational effort resultant in crowded appearance of the pulmonary vasculature . It is conceivable that one may have interpreted this to include multiple nodular densities but this can not be confirmed by today 's chest examination with improved inspirational effort .
    OUTPUT:
    
Cardiomegaly , thoracic aortic elongation in patient with history of stroke . No signs of acute CHF or acute infiltrates .
