Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Left chest wall pacemaker generator with dual chamber leads . The right atrial lead projects over the midline and the presumed ventricular lead terminates over the central mediastinum rather than near the cardiac apex as is usually seen . Heart size is mildly enlarged . Represent redistribution and central pulmonary vascular congestion is noted . Mild interstitial edema is seen . No large pleural effusion . Small right pleural effusion is likely . No pneumothorax .
    OUTPUT:
    
1 . Mild pulmonary edema with trace right pleural effusion . 2 . Ventricular lead of the pacemaker terminates in the midline , and is typically seen closer to the cardiac apex . Recommend correlation with pacemaker interrogation .
