Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There is moderate cardiac enlargement . Indistinct pulmonary vascular markings are noted suggesting vascular congestion . On the frontal , there is mild retrocardiac opacity . On the lateral view , there is increased opacity projecting over the posterior lung bases . While some this could be due to overlying soft tissues though underlying parenchymal consolidation is also possible . Right PICC tip seen over the upper SVC .
    OUTPUT:
    
Cardiomegaly with pulmonary vascular congestion . Presumably left basilar opacity could be in part due to atelectasis and overlying soft tissues , superimposed infection can not be excluded .
