Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The endotracheal tube ends 2 .6 above the level of the carina , not significantly changed . There is partial visualization of a left - sided pacemaker with associated right atrial and right ventricular leads . An enteric catheter courses below the level of the diaphragm and out of field of view inferiorly . A right internal jugular central venous catheter ends in the low SVC . Lung volumes remain low . Moderate interstitial pulmonary edema has slightly improved . Massive cardiomegaly is not significantly changed . Note is made of a calcified left ventricular aneurysm , as before . The mediastinal contours are not significantly changed . Small bilateral pleural effusions are thought likely . Dense retrocardiac opacification is likely atelectasis . There is no pneumothorax .
    OUTPUT:
    
1 . Right internal jugular central venous catheter ends in the low SVC . No pneumothorax . 2 . Decreased moderate interstitial pulmonary edema with unchanged moderate - to - severe cardiomegaly . 3 . Dense retrocardiac atelectasis . 4 . Likely small bilateral pleural effusions .
