Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The patient is status post sternotomy and coronary artery bypass graft surgery . The heart is normal in size . The mediastinal and hilar contours appear within normal limits . The left lung now appears clear with resolution of pulmonary edema and pleural effusion on the right . There is persistent opacification , particularly posteriorly , suggesting a pleural effusion of small to moderate size on the right , potentially with some loculation . Associated residual atelectasis is likely but substantially improved . There is also a more generalized persistent right - sided interstitial abnormality but markedly reduced .
    OUTPUT:
    
Marked improvement in pleural effusions and pulmonary edema but with persistent right - sided effusion , potentially with some loculation and residual unilateral interstitial abnormality . Short - term follow - up with chest CT is recommended to reassess previously noted nodular opacities .
