Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Left - sided pacemaker is again seen , with leads unchanged position compared to prior . The ventricular tip most likely abuts the right ventricular wall . Heart size is upper limits of normal . Mediastinal and hilar contours are mildly enlarged , with apical redistribution of the pulmonary vessels and bilateral small to moderate pleural effusion , likely due to pulmonary edema . Right lung linear opacities are likely due to atelectasis . There is no evidence for pulmonary consolidation or pneumothorax . Aortic calcification appears unchanged .
    OUTPUT:
    
1 . Left - sided pacemaker with leads in expected location . 2 . Pulmonary edema and bilateral small to moderate pleural effusion .
