    INPUT: The patient is status post sternotomy . There is mild to moderate cardiomegaly . Compared with the prior film , there is new CHF , with upper zone redistribution , thickening of the minor fissure , and diffuse vascular blurring . More patchy opacity at the right cardiophrenic region could reflect vascular plethora and atelectasis , but the possibility of an early infiltrate can not be excluded . Otherwise , no consolidation . No gross effusions .
    OUTPUT:
    
Findings consistent with CHF . Patchy at the opacity in the right cardiophrenic region could due to CHF , but the possibility of an early pneumonic infiltrate can not be entirely excluded . Attention to this area on followup films is requested .
