Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Heart size is at least moderately enlarged . Assessment of the cardiac size however is difficult to discern exactly due to the presence of small to moderate bilateral pleural effusions , left greater than right . The aorta is calcified and tortuous . There is moderate pulmonary edema . Bibasilar airspace opacities likely reflect compressive atelectasis . No pneumothorax is detected . Multilevel degenerative changes are seen in the imaged thoracolumbar spine with loss of height of a vertebral body at the thoracolumbar junction which is age indeterminate .
    OUTPUT:
    
Moderate congestive heart failure with small to moderate size bilateral pleural effusions , left greater than right , and bibasilar compressive atelectasis .
