Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Compared to the prior film , the Swan - Ganz catheter is been removed . No pneumothorax is detected . Again seen is hyperinflation suggestive of background COPD . Also again seen is cardiomegaly , with prominence of the mediastinal silhouette and slight enlargement of the azygous vein . The aorta is calcified and unfolded . The lateral view demonstrates extensive coronary artery calcification . Mild prominence of the hila is similar to the prior study . There is upper zone redistribution , the increased interstitial markings , peribronchial thickening and diffuse vascular blurring , consistent with CHF . The appearance is similar , perhaps slightly more pronounced , than on the prior film . Small bilateral effusions are present . There is increased retrocardiac opacity , consistent with left lower lobe collapse and / or consolidation , though the hemidiaphragm remains faintly visible , as before . There is minimal atelectasis at the right lung base , new compared with the prior study . Incidental note is made of marked narrowing of the right shoulder acromial humeral distance , consistent with a chronic rotator cuff tear .
    OUTPUT:
    
1 . Cardiomegaly . 2 . CHF with interstitial edema . 3 . Slight enlargement of the azygous vein , consistent with right heart failure . 4 . Small effusions with bibasilar atelectasis . 5 . Probable background COPD . 6 . Chronic right shoulder rotator cuff tear .
