Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: 2 lead left - sided pacer device is seen , unchanged in position . There is a small to moderate left pleural effusion with overlying atelectasis . Left basilar opacity may be due to combination of pleural effusion and atelectasis , underlying consolidation is not excluded . Left basilar opacity is grossly stable to possibly minimally increased as compared the prior study . Prominence and indistinctness of the hila suggest vascular engorgement . Right base airspace opacity is increased as compared to the prior study , which may relate to fluid overload , however , underlying infection , pulmonary hemorrhage , or aspiration is not excluded . The cardiac and mediastinal silhouettes are stable . Mild anterior wedging of a lower thoracic vertebral body is grossly stable compared to the prior study . No obvious rib fracture there is seen , however , dedicated rib series or CT is more sensitive .
    OUTPUT:
