Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A left PICC tip terminates deep within the right heart , likely within the right ventricle , and should be withdrawn approximately 9 cm . Right - sided dual lumen central venous catheter tip terminates within the proximal right atrium . Mild cardiomegaly is unchanged , and the mediastinal and hilar contours are unremarkable . Retrocardiac opacification could reflect atelectasis though infection is not excluded . Previously noted bilateral pleural effusions appear to have nearly resolved , with likely a small residual left - sided pleural effusion present . There is no pulmonary edema or pneumothorax . No acute osseous abnormality seen .
    OUTPUT:
    
1 . Left PICC terminates within the deep right heart , possibly within the right ventricle , and should be withdrawn by approximately 9 cm . 2 . Retrocardiac opacification may reflect atelectasis . Infection can not be excluded . 3 . Interval decrease in size of previously noted bilateral pleural effusions , with likely a trace amount of left - sided pleural effusion remaining .
