Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: As noted previously , dual - chamber pacemaker is in stable and standard course and position from a left subclavian approach . There is an apparent single abandoned lead from a right subclavian approach , which is situated within the anterior right chest wall . There is venous hypertension and cepphalized flow . The pulmonary vessels are indistinct . Linear atelectasis is seen at the right lung base . There is a tortuous atherosclerotic aorta . The cardiac silhouette remains massively enlarged . Prior bowel surgery is evident . No effusion or pneumothorax is noted . A ring - like density projects over the central aspect of a mid thoracic vertebral body which is not clearly evident on prior imaging . No displaced fractures are noted . There are no compression vertebral fractures .
    OUTPUT:
    
Mild interstitial edema , likely cardiogenic in etiology . Recommend repeat radiography after appropriate diuresis . A ring - like structure over the vertebral body is indeterminate etiology or clinical significance . It could be artifactual . Dedicated thoracic spine radiographs would likely be useful in short order to further corroborate the finding as truly within the vertebral body to assess for reproducibility .
