Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The cardiac , mediastinal and hilar contours appear stable . The heart is again moderately enlarged . The aorta is markedly tortuous . The lung bases appear better aerated than on the prior examination , although on this study , there is perhaps mild upper zone re-distribution of pulmonary vasculature suggesting pulmonary venous hypertension . Pleural effusions have mostly or fully cleared . There is marked kyphotic curvature with similar but incompletely assessed deformities at the thoracolumbar junction .
    OUTPUT:
    
Findings which may suggest mild vascular congestion but generally improved aeration at the lung bases including substantial resolution of suspected pleural effusions .
