Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The patient is status post sternotomy and both mitral and aortic valve replacements . Moderate cardiomegaly is unchanged . The mediastinal and hilar contours appear stable . There is new mild - to - moderate relative elevation of the right hemidiaphragm which suggests volume loss and a patchy opacity in the right lower lobe has increased and is worrisome for pneumonic consolidation . There is probably also some degree of new opacification in the right middle lobe . A vague opacity is also new in the right suprahilar region in the right upper lobe , potentially an early focus of pneumonia . There is no definite pleural effusion .
    OUTPUT:
    
Findings suggest multifocal pneumonia involving the right lung .
