    INPUT: Left - sided dual - chamber pacemaker device is noted with leads terminating in right atrium and right ventricle . The heart is moderate to severely enlarged with a left ventricular predominance . The aorta is diffusely tortuous and calcified . There is mild pulmonary edema and small bilateral pleural effusions . More focal patchy opacities in the lung bases could reflect atelectasis though infection or aspiration can not be excluded . Left apical pulmonary parenchymal scarring appears similar compared to the prior exam . Compression deformities of multiple vertebral bodies at the thoracolumbar junction are noted , some of which appear to have been present on the CT of the lumbar spine from ___ .
    OUTPUT:
