Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Two transvenous pacemaker leads , continuous from the left pectoral generator , are unchanged in position since ___ when they were newly inserted . The right atrial lead follows the usual course . The right ventricular lead is oriented obliquely upward to the anterior wall of the right ventricle at the origin of the pulmonary outflow tract . Moderate right pleural effusion and thickening , are chronic , accounting for stable volume loss in the right lung since ___ . There is no left pleural effusion , pneumothorax , or mediastinal widening . Mild cardiomegaly is chronic . Previous mild pulmonary edema in the right lung has changed in distribution but not entirely cleared , and pulmonary vascular congestion persists .
    OUTPUT:
    
No change since ___ in non standard position of right ventricular transvenous pacemaker lead close to the pulmonary outflow tract . No evidence of complications related to lead insertion . Mild pulmonary edema persists in the right lung , probably influenced by restrictive pleural thickening . Chronic mild cardiomegaly and pulmonary vascular congestion .
