    INPUT: Frontal and lateral views were obtained . Low lung volumes result in bronchovascular crowding . The pacemaker leads end in the expected locations of the right atrium and right ventricle . There is no focal consolidation , pleural effusion or pneumothorax . Right basilar atelectasis . Heart is borderline enlarged . Mediastinal silhouette and hilar contours are normal allowing for lung volumes with prosthetic valve and intact median sternotomy wires .
