Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A portable frontal chest radiograph again demonstrates an incompletely imaged left chest pacemaker with the single lead overlying the right ventricle . An endotracheal tube in proper position . The right jugular catheter projects over the right mediastinum , but is secondary to patient rotation and confirmed to be in the vein on subsequent CT . There is no pneumothorax . The remainder is unchanged , demonstrating a moderate right pleural effusion .
    OUTPUT:
    
1 . No pneumothorax . Previous reference to a left pneumothorax is explained by likely misinterpretation of skin folds , and is confirmed by subsequent CT chest . 2 . Otherwise unchanged chest radiograph , demonstrating a moderate right pleural effusion .
