    INPUT: Patient is status post median sternotomy and CABG . Heart size remains mildly enlarged but unchanged . The aorta is tortuous . Mild interstitial pulmonary edema is worse in the interval . More focal patchy opacity in the right lung base may reflect asymmetric pulmonary edema or atelectasis , however early infection is not excluded in the correct clinical setting . Small bilateral pleural effusions have decreased in size compared to the prior study . There is no pneumothorax . No acute osseous abnormality is detected .
    OUTPUT:
    
Mild interstitial pulmonary edema , worse in the interval . Decreased small bilateral pleural effusions . More focal right basilar patchy opacity may reflect asymmetric pulmonary edema or atelectasis , but early infection is not excluded in the correct clinical setting .
