Since ___ , lung volumes are much lower . Dense left retrocardiac opacity likely represents atelectasis . Pulmonary vascular congestion is mild . No sizable pleural effusion or pneumothorax . Heart size is mildly enlarged , with minimal pneumopericardium . Widened mediastinum is consistent with postoperative change .
