    INPUT: Moderate enlargement of the cardiac silhouette persists . The aorta remains tortuous and diffusely calcified . A moderate to large layering right pleural effusion and small left pleural effusion are present , with the right pleural effusion likely larger in size in the interval . Lung volumes are low with patchy opacities the lung bases likely reflective of compressive atelectasis . Crowding of the bronchovascular structures is noted with probable mild pulmonary vascular congestion . No large pneumothorax is demonstrated . Right PICC has been removed .
