Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lungs are well - expanded . Compared with prior exam there is interval worsening of vascular congestion , more prominent in the right lung . Mild cardiomegaly is unchanged . The small bilateral pleural effusions are slightly improved from prior . Retrocardiac opacities are stable from prior and likely atelectasis although superimposed infectious process can not be excluded . The left - sided transvenous pacemaker is redemonstrated with leads ending in appropriate position .
    OUTPUT:
    
1 . Worsening asymmetric pulmonary vascular congestion , right worse than left , on the background of mild cardiomegaly . 2 . Poor aeration of the left lower lung and retrocardiac opacities are likely a combination of atelectasis and pleural effusion . However superimposed infectious / inflammatory process can not be excluded .
