    INPUT: Portable upright chest radiograph was provided . A left chest wall dual - lead pacemaker is seen with leads in the right ventricle and right atrium . Median sternotomy wires are intact . Lung volumes are slightly low . There is no focal consolidation , pleural effusion or pneumothorax . There is no evidence of pulmonary edema . Prominent interstitial markings at the lung bases are unchanged since the prior studies , likely representing NSIP and better assessed on the recent chest CT . The cardiomediastinal silhouette is notable for a tortuous and calcified aorta . The heart is minimally enlarged .
    OUTPUT:
    
No acute cardiopulmonary process . Prominent interstitial markings at the bases likely reflect NSIP and are better assessed on the recent chest CT .
