Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: PA and lateral chest views have been obtained with patient in upright position . The heart is mildly enlarged . The configuration demonstrates a relative prominence of the left ventricular contour to the left and posteriorly . The thoracic aorta is mildly widened and elongated , but no local contour abnormalities are present . The pulmonary vasculature demonstrates an upper zone redistribution pattern , but there is no evidence of interstitial or alveolar edema and the lateral and posterior pleural sinuses are free . A permanent pacer is seen in left anterior axillary position connected to two intracavitary electrodes with termination points compatible with right atrial appendage and right ventricular apical portion . Skeletal structures demonstrate a mildly accentuated kyphotic curvature and somewhat demineralized vertebral bodies , but no evidence of compression fracture or other skeletal abnormalities in the thoracic area . Patient was unable to elevate left arm for the lateral view related to recent pacemaker placement . Our records do not include a previous chest examination available for comparison .
    OUTPUT:
    
Unremarkable position of dual intracavitary electrode pacemaker system . No evidence of pneumothorax .
