    INPUT: A double lumen left - sided dialysis catheter terminates at the cavoatrial junction . The left costophrenic angle remains blunted , likely secondary to trace pleural effusion versus chronic pleural thickening . There is no lobar opacity , right pleural effusion , pneumothorax , or pulmonary edema . Moderate cardiomegaly is chronic and slightly less prominent than on the prior examination . The aortic arch is calcified .
    OUTPUT:
    
No acute cardiopulmonary process . Slight interval decrease in now moderate cardiomegaly .
