    INPUT: The patient is status post median sternotomy and CABG . Mild cardiomegaly is demonstrated . The aortic knob is calcified . Mediastinal contours otherwise are unremarkable . There is mild perihilar haziness and vascular indistinctness compatible with mild pulmonary edema . Small bilateral pleural effusions are noted with bibasilar airspace opacities likely reflective of compressive atelectasis . No pneumothorax is seen though assessment of the lung apices is somewhat obscured due to the patient 's chin projecting over this region . Deformity of the left proximal humerus is partially imaged and reflective of a remote healed fracture .

Mild congestive heart failure with small bilateral pleural effusions and bibasilar compressive atelectasis .
