Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: AP and lateral views of the chest demonstrate dual lead left - sided pacemaker in unchanged position with leads in the right atrium and right ventricle . Since the prior study , there has been interval development of a moderate left pleural effusion , as well as blunting of the right costophrenic angle representing a small pleural effusion , perhaps slightly increased since the prior . Additionally , there is persistence of curved opacity along the lateral right pleural surface which is unchanged since the prior study and could be due to a loculated pleural effusion or pleural thickening . There is also evidence of pulmonary vascular congestion and fluid overload with pulmonary edema , more prominent on the right . There is no pneumothorax . There is atelectasis at the left lung base , however an infectious component can not be completely excluded .
    OUTPUT:
    
1 . Bilateral pleural effusions , moderate on the left and trace on the right with likely a loculated component on the lateral right pleural surface . 2 . Pulmonary edema , more prominent on the right . 3 . Left basilar atelectasis . Underlying infectious component can not be completely excluded .
