    INPUT: Compared with chest radiograph on ___ , a right chest wall biventricular pacemaker defibrillator generator is stable in position , with right ventricular pacer defibrillator , and left ventricular pacer leads in standard position . The right atrial pacer lead appears more medial than typically seen , however is stable from priors . There has been interval decrease in pulmonary vascular congestion compared with prior . There is no pulmonary edema or pleural effusion . The lungs are clear without focal consolidation . No pneumothorax . Mild cardiomegaly is unchanged . Left chest port is unchanged , terminating at the cavoatrial junction .
    OUTPUT:
