    INPUT: AP and lateral chest radiographs demonstrate enlarged heart with relative increase in density bilaterally over the lower lung fields , minimally decreased in conspicuity relative to prior chest radiograph dated ___ , likely secondary to overlying soft tissue . There is mild pulmonary edema , perhaps slightly improved in the interval . Bibasilar patchy opacities are likely reflective of atelectasis . There is no large pleural effusion or pneumothorax . Imaged osseous structures and upper abdomen are without an acute abnormality . Multiple clips are again noted within the left axilla .
    OUTPUT:

Markedly enlarged cardiac silhouette stable relative to prior study with mild pulmonary edema , perhaps slightly improved . Bibasilar atelectasis , though pneumonia is difficult to exclude .
