Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: PA and lateral chest radiograph demonstrates a left subclavian approach hemodialysis catheter , its tip which projects over the anticipated location of the right atrium . Heart size is upper limits of normal in size , likely exaggerated by slightly low lung volumes . Blunting of the right costophrenic angle is consistent with a small to moderate pleural effusion . There is mild central pulmonary vascular congestion without overt pulmonary edema . There is no pneumothorax . Imaged upper abdomen is unremarkable . Vascular stent projects over left upper extremity .
    OUTPUT:
    
Mild central pulmonary vascular congestion without overt pulmonary edema . Small to moderate right pleural effusion . Left - sided dual lumen central venous catheter with distal tip in the right atrium .
