Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A right internal jugular transvenous pacer terminates in the right ventricle . A CoreValve is present within the aortic valve . There are diffuse interstitial opacities consistent with plulmonary edema . A more conlfuent area of opacification is noted in the right upper lobe . The cardiac silhouette is mildly enlarged but unchanged . There is no pleural effusion or pneumothorax . The mediastinal contours are normal . The imaged upper abdomen is unremarkable .
    OUTPUT:
    
1 . Moderate pulmonary edema . More confluent opacity in the right upper lobe may reflect gravitational edema versus aspiration . 2 . Satisfactory position of a right transvenous pacer .
